AstroZap Visual Baader Solar Filter for 120 mm - 130 mm OD Telescopes - AZ1001-1

To ensure that the solar filter you buy will fit properly, please take a few moments and measure the outside diameter of your telescope, spotting scope or binoculars before you order. Remember, the solar filter needs to fit snugly around the front of the tube assembly that holds the optics. If the filter is slightly larger than its diameter, the filter can be made to fit by the addition of self-stick felt spacers to the inside of the cell. However, if the filter is too small it will not fit, and that would be a shame. So please, measure before you order. Thanks.AstroZap Baader Film Solar Filterfor 120 mm - 130 mm TelescopesView a solar eclipse or sunspots for improved observations of the Sun with the AstroZap Baader Film Solar Filter! Produced in Germany, this filter is made from Baader AstroSolar film which has often been considered a leader in solar technology. Approved by the National Bureau of Standards for eye safety, the AstroZap solar filter will protect your eyes from the Sun's harmful rays. This solar filter is designed for telescopes with an outer diameter of 120 mm to 130 mm.Astrozap mounts the AstroSolar film in an aluminum cell. To install, you simply slide the filter cell over the end of your telescope and tighten the three thumbscrews so that the filter is firmly attached to your telescope. With the filter securely in place, you can look at the Sun through a standard eyepiece. Just remember not to look through your finderscope unless it has its own little filter installed! Most observers remove their finder altogether so as not to be tempted in the first place since it is relatively easy to center the Sun in your eyepiece once you've learned a trick or two.When viewed through an Astrozap solar filter, the Sun appears neutral white. Other films and some glass filters produce a blurry bluish or reddish solar image, thereby cutting out part of the spectrum. Especially with an orange sun, it is very hard to see faculae regions which are visible predominantly in the blue part of the spectrum.Due to its neutral color balance, the use of an Astrozap Baader Solar Filter enables the use of various color (or interference) filters, allowing the observer to concentrate on certain spectral passbands for investigations of different layers within the solar "atmosphere".Eye safetyAstroSolar™ is essentially free from pinholes, since - other than with even the most expensive glass filters - it is coated on both sides so that the chance of two pinholes overlapping each other is extremely faint. Pinholes do appear, but to 1 out of 10000 only in optical density 2.5! Baader AstroSolar™ safety film has been approved for eye safety by the National Bureau of Standards in Germany, the PTB. Unlike any other Solar Filter on the market, AstroSolar™ is CE-tested according to EG-Norm 89/686 and EN 169/92 ( notified body 0196). All processes connected to this product have been thoroughly tested. Coatings are inspected constantly for consistency to ensure your eye safety!Sizing your solar filterEach solar filter is designated in two ways—by the typical telescope or aperture it was designed for, and by the outside diameter range of the telescope it will fit. Before you order your solar filter, take a minute and measure the outside diameter (OD) of your telescope so that you can be sure you are ordering the right one. Each filter has 10mm of wiggle room. Three thumbscrews are provided to snug up the fit. Once your solar filter arrives, slip it over the end of your scope and tighten the thumbscrews to make sure it fits properly. This is important, as an ill-fitting solar filter is not something you want to mess around with. If the filter does not fit, or you have any other concerns, contact our sales department and we will work with you to solve the problem. Don't wait until that once-in-a-lifetime solar eclipse to find out your solar filter doesn't fit!

AstroZap Visual Baader Solar Filter for 165 mm - 175 mm OD Telescopes - AZ1013-1

To ensure that the solar filter you buy will fit properly, please take a few moments and measure the outside diameter of your telescope, spotting scope or binoculars before you order. Remember, the solar filter needs to fit snugly around the front of the tube assembly that holds the optics. If the filter is slightly larger than its diameter, the filter can be made to fit by the addition of self-stick felt spacers to the inside of the cell. However, if the filter is too small it will not fit, and that would be a shame. So please, measure before you order. Thanks.AstroZap Baader Film Solar Filterfor 165 mm - 175 mm TelescopesObserve a solar eclipse or sunspots with enhanced clarity with the AstroZap Baader Film Solar Filter! Assembled in Germany, this filter has been expertly crafted using Baader AstroSolar film, one of the most renowned names in solar astronomy. Approved by the National Bureau of Standards for eye safety, the AstroZap solar filter will protect your eyes from the Sun's harmful rays. This solar filter is designed for telescopes with an outer diameter of 165 mm to 175 mm.Astrozap mounts the AstroSolar film in an aluminum cell. To install, you simply slide the filter cell over the end of your telescope and tighten the three thumbscrews so that the filter is firmly attached to your telescope. With the filter securely in place, you can look at the Sun through a standard eyepiece. Just remember not to look through your finderscope unless it has its own little filter installed! Most observers remove their finder altogether so as not to be tempted in the first place since it is relatively easy to center the Sun in your eyepiece once you've learned a trick or two.When viewed through an Astrozap solar filter, the Sun appears neutral white. Other films and some glass filters produce a blurry bluish or reddish solar image, thereby cutting out part of the spectrum. Especially with an orange sun, it is very hard to see faculae regions which are visible predominantly in the blue part of the spectrum.Due to its neutral color balance, the use of an Astrozap Baader Solar Filter enables the use of various color (or interference) filters, allowing the observer to concentrate on certain spectral passbands for investigations of different layers within the solar "atmosphere".Eye safetyAstroSolar™ is essentially free from pinholes, since - other than with even the most expensive glass filters - it is coated on both sides so that the chance of two pinholes overlapping each other is extremely faint. Pinholes do appear, but to 1 out of 10000 only in optical density 2.5! Baader AstroSolar™ safety film has been approved for eye safety by the National Bureau of Standards in Germany, the PTB. Unlike any other Solar Filter on the market, AstroSolar™ is CE-tested according to EG-Norm 89/686 and EN 169/92 ( notified body 0196).

Atik 16200 APS-H Color CCD Camera - ATK0155

Atik 16200 APS-H Sized Color CCD CameraThe Atik 16200 Imaging Camera features the KAF-16200 Color CCD sensor, which offers a large 35mm diagonal and 6 µm pixels to make this camera a great match for a wide range of telescopes. However, this amazing APS-H-sized sensor is not the only upgrade to the Atik 16200, it has a whole new body, too. Improvements include a new dual-stage Peltier cooling system, heat sink, blade shutter, and a cool lightweight casing that will serve you well.KAF-16200 Full Frame APS-H CCD SensorThe ON-Semi KAF−16200 is a single output, high performance CCD image sensor with 4500 (H) x 3600 (V) photoactive pixels. Each pixel contains anti−blooming protection by means of a lateral overflow drain, thereby preventing image corruption during high light level conditions, and microlenses are added for improved sensitivity. Each of the square 6.0 µm pixels are selectively covered with red, green, or blue pigmented filters for color separation. The 16200 sensor utilizes a transparent gate electrode to improve sensitivity compared to the use of a standard front side illuminated polysilicon electrode.The full frame KAF-16200 has a large 35mm diagonal, and can be used with a filter wheel that supports 2" filters. The large sensor size and generous 6 µm pixels makes the Atik 16200 suitable for a wide range of telescopes, whether you are using a fast scope to capture wide field celestial views, or telescopes with longer focal lengths to image the intricate details on even the smallest and faintest of objects. Whatever your astrophotography style, the large size of the resulting images give you the freedom and flexibility to zoom in and take a closer look at regions of interest with the level of detail you’d expect from your main target.Atik 16200 Camera Body HighlightsThe full frame, APS-H sized sensor is housed in a sealed chamber that has been argon-purged to keep moisture and dust particles out. Inside the 16200 camera body is a dual-stage Peltier and a powerful heatsink for amazing cooling performance. With a typical delta of -45C and a max of -50ºC, you'll enjoy low noise results even when imaging on warm summer nights.Atik's high performance electronics power the sensor, which has a read noise of only 9e-. A reimagined blade shutter is a design change for the 16200, which will provide consistent and reliable results for many years to come.

Atik Infinity Video Camera - Monochrome - ATK0144

Atik Infinity Monochrome Video Camera with Custom Built-In Software ApplicationThe Atik Infinity, with its sensitive Sony ICX825 sensor, is a dedicated video camera designed to be used by the beginner! The custom built-in software makes everything easy, from tracking and adjusting for field rotation to real time stacking so you can take multiple short exposures with ease. With the Atik Infinity, there is no need for a high end equatorial mount capable of precise tracking. No polar alignment is necessary, and precise tracking is not required, either! This means that users of entry level equatorial mounts with lower end drives can take images with the Infinity and get good results. Why? Because the Infinity software is smart enough to throw out frames with tracking errors, leaving you only good ones in the stack.The Atik Infinity is shaped like a small digital camera for a reason. The slim rectangular shape was required to hold the high quality circuit board chosen for the Infinity camera, and it can easily clear when swinging through fork-mounted telescopes.Even though the Atik Infinity was designed for the beginner, amateur astronomers with more experience would love it as well. Because the Infinity acquires objects quickly, it is the perfect tool for outreach. Just imagine being able to have someone step up to the telescope and view a much more detailed image of an object in almost real time. In fact, the Infinity is so streamlined and easy to use, astronomers could show newbies the image through the eyepiece, and then what it looks like through the magic of a sensitive video camera. Astro-Imagers who still enjoy showing family and neighbors the Universe can also use the Infinity as an autoguider, so that while they are shooting with the "big boy" camera, curious onlookers can enjoy the view at the Infinity. Atik's Introduction of the Infinity CameraThe Atik Infinity is the first Atik Camera dedicated to video astronomy, boasting both the speed and sensitivity required for this rewarding technique. Through new, intuitive, in-house software, the Infinity brings the wonders of the deep sky to a screen in just seconds.The Infinity features a Sony ICX825 sensor embedded with EXview HAD CCD II™ technology for outstanding sensitivity and Quantum Efficiency at a resolution suited to near real time viewing. The generous 6.45 µm pixel size is well-suited to a broad range of telescopes while the slim, rectangular design ensures the camera can clear the base on fork-mounted scopes. This makes the Infinity well-suited to a huge variety of setups, from those just starting out right through to the professional observatory.New SoftwareAlongside the Infinity is a custom software application dedicated to video astronomy. It features a simple, intuitive user interface for optimum usability without compromising on camera control or performance. Live continuous stacking removes background noise so you see more of what matters, and flexible histogram adjustments make sure you never miss a detail.Integrated broadcasting features take the hassle out of sharing your sky, and voice over and live web chat create a truly interactive experience, straight out the box. The software also features session record and interactive replay so you remain in full control of the display when sharing your sessions with family and friends.Live continuous stackingFlexible histogram control, including auto-stretch functionsLive YouTube broadcast integrationInteractive session replayFocus assist and monitoring toolsSave to FITs, PNG and JPG formats The Perfect Outreach ToolVideo astronomy is ideally suited for use in public outreach programs and educational settings.

Atik GP Monochrome CCD CameraThe Atik GP excels as both a planetary camera and as a guide camera. Its compact size and light weight make it a joy to use on telescopes large and small. The sensor used is the fantastically sensitive 1.3 million pixel ICX445 EXview II CCD from Sony. The GP is capable of up to 30 frames per second and will download both 8-bit data with the convenience of saving to standard avi file format, or 12-bit for full dynamic range as Tif and Fits format. When used with the included GPAcquire software the camera is fully configurable with gain, region of interest, data format and a myriad of other settings enabling optimal planetary, solar and lunar imaging. Data can be save direct to disk or initially to memory to optimise frame rates with slightly slower hardware.Slowing things down a little the advanced passive cooling allows images of 1 ms to several seconds to be collected, ideal for guiding. The camera is fully compatible with existing Atik software so can be used with the (included) Capture software as well as plug ins for Maxim DL, AstroArt, and more though the ASCOM camera interface. Controlled this way it behaves much the same as Atik's bigger cameras and will allow binning and sub framing. Guiding corrections are passed to the mount using an ASCOM interface. This is presents many advantages over the older ST4 guide port method including ease of set up, logging, and precision of guide corrections. But it does require that the mount is ASCOM compatible (as most modern mounts are) and linked to the computer. Guiding older mounts may still be possible with an USB to ST4 converter box, ask your dealer.The GP does not have the active cooling of the Atik Titan so its potential for deep sky imaging is more limited, but it can be used to image the brighter deep sky objects.

Baader LRGB CCD Filter Set - 1.25" Mounted - FLRGB-1

Baader 1.25" LRGB CCD Filter SetThis LRGB CCD Filter Set from Baader Planetarium provides enhanced color separation and image quality without pesky halos. Baader has designed these high-performance LRGB Filters using a thorough testing program and coating-stack design. Baader has partnered with the world's leading thin film coating company to produce transmission curves that border on the ideal. This set contains four round 1.25" filters: one luminance (L) filter, and one each, red, green, and blue filter.Their ultra steep cutoffs and high transmission, >95% allowed Baader to achieve something no other RGB filter set has, - they are able to effectively separate the important H-Beta and O-III lines. The Baader Blue filter passes virtually all of the H-Beta lines, while the Green filter is able to capture all of the O-III line, without encroaching into the H-Beta line. None of the light is wasted by either filter. In this way, O-III is represented as it should be, a teal (blue-green) color, and H-Beta is captured solely in the blue. This novel degree of separation is achieved, along with high transmission for both lines. In addition, the Green and Red filter passbands nearly touch, leaving only a sharp notch to block out the primary Mercury/Sodium light pollution line at 580 nm. The high transmission everywhere else delivers the shortest combined exposures possible with every detector.The high optical quality of the Baader narrowband filters guarantees no loss in sharpness or contrast. Each substrate is fine-optically polished plane parallel to deliver a smooth and accurate 1/4 wavefront over the entire surface. Each filter is blocked and polished individually, not cut out of a larger plate of glass. The special custom polishing operation sets Baader filters apart from other filter manufacturers.Coatings are professionally applied in Germany by the most sophisticated equipment available today, ensuring high consistency for bandpass cutoffs, transmission, and out of band blocking. The anti-reflection coatings are evenly balanced on both sides of the filters to reduce surface stresses and prevent deformation of the substrates. The ultra-hard ion beam deposition ensures the coatings will never degrade from use or normal cleaning. Baader coats each filter individually. Baader filters remain sealed at their coating edges for a long life without degradation. Though more costly, this process avoids coating failures resulting when filters are "biscuit cut" from bulk-coated sheet glass, leaving ragged edges for moisture to penetrate, and cause coatings to peel. Baader filters are intended for a lifetime of real-world use!

Baader Planetarium 4.5mm MORPHEUS 76 Degree Eyepiece - MORPH-4

Baader 4.5mm Morpheus 76° Eyepiece with 1.25”/2” Barrel and Cordura CaseThe 4.5mm Morpheus Eyepiece, by Baader produces immersive views with generous eye relief, 76° field of view, and Phantom Coatings on it's rare earth glass. Enjoy sharp stars across the field even with fast scopes. 1.25” &and 2” barrels deliver the ultimate in flexibility.Encased in sealed housing for water resistance, all lens edges have been blackened and optimized for bino-viewing. Building on the success of Baader’s legendary Hyperion eyepieces, Morpheus provides an even brighter, wider view that’s sharp to the edge of the field, even when paired with the fastest telescope systems.Unique Optics for Spacewalk ViewingThe “spacewalk” feel is a huge trend in high end eyepieces because it provides a truly immersive experience. In the past, this unique spacewalk sensation was only available on the widest field eyepieces that routinely cost $500 and more. To provide the same feeling at a more affordable price point, Baader’s optical engineers conducted years of research and testing. They determined that the eyepiece’s design, eye relief, and viewing comfort are responsible for that spacewalk feel—not just a super wide field of view.With Morpheus’ 76-degree field of view, you get immersive views that remain pinpoint sharp all the way to the edges. Unlike other wide field eyepieces, Morpheus is free of distortion and never feels like you’re looking through a fishbowl. In creating Morpheus, Baader has paid meticulous attention of every detail of the optics. They’ve enhanced and perfected their signature Phantom Coating Group of optical coatings for maximum light transmission. What’s more, Morpheus features rare earth glasses, blackened lens edges, and a ray-traced internal baffling to eliminate any internal reflections.New Mechanical DesignMorpheus is just as impressive on the outside. To provide you with maximum versatility, Morpheus keeps its weight to an absolute minimum and features a sleek, streamlined silhouette—perfect for use with binoviewers.One of the pain points in most premium eyepieces is the barrel. Smooth barrels aren’t as secure inside your star diagonal, but wide undercuts cause headaches when you’re trying to quickly swap eyepieces in the dark. The Baader Morpheus solves this dilemma. Its innovative new “safety kerfs” provide an enhanced grip and protect against mishaps in the field, but are shallower than undercuts for easy eyepiece swaps. You’ll find these safety kerfs on the 1.25” and 2” barrels, so you can take advantage of this feature with any telescope. For added protection, Morpheus’ rubber exterior features a waffle-patterned grip ring.Perfect for AstrophotographyFor a night of visual observing and imaging, Baader has perfected the imaging projection eyepiece. Like the bestselling Hyperion eyepiece before it, Morpheus features a hidden M43 thread tucked away under the removable rubber eyecup. Slide the eyecup off and you’re ready to attach just about any camera. Baader’s optional M43 adapters offer a super secure connection with minimal vignetting.Bonus Features and AccessoriesIn addition to its stunning views, the Baader Morpheus provides a superb user experience in the field thanks to its bonus features and included accessories. One thing you’ll notice on your first night out is the photoluminescent engraving on the eyepiece barrel. With this handy feature, the eyepiece’s name and focal length are easy to spot thanks to a subtle glow. Forget about searching for a flashlight or fumbling in the dark. With Morpheus, you’ll always have the right eyepiece close at hand. (Don’t worry—this special engraving won’t disturb your night vision.)Every Morpheus eyepiece includes two eyecups: a standard foldable rubber eyecup and a winged eyecup. The winged option is perfect for use with binoviewers, during daytime sessions, or to block out stray light from a pesky streetlamp. Finally, you’ll also receive a handy eyepiece holster that attaches to your belt so your Morpheus is always protected and close at hand.

Baader Planetarium 1.25" 90º Prism Star Diagonal - PRISM-1

Baader 90º Prism Star Diagonal with 1.25" Nosepiece &and Eyepiece HolderOne of the main features of the Baader T2 90° Star diagonal is the large free aperture it offers, but this diagonal is also amazingly flexible in its ability to adapt to almost any telescope system on the market today, without the usual problems of bottlenecking and vignetting during challenging applications. It is for this reason that Baader offers their T2 System diagonal without adapters so that you can have the freedom of designing a diagonal that fits your needs perfectly.The telescope side of Baader T2 diagonals accepts an entire armada of adapters, including standard items like 1.25" or 2" focuser, or more esoteric items like an original M44 Zeiss thread to connect to a Russian Mak or a Vixen OTA. On the eyepiece side many people use the Baader Quick Change Ring #6 so that they can mount the Mark V binocular viewer in a way that achieves the shortest possible back focus distance between their telescope and the binocular viewer, but of course you can do whatever you need to do. .that's the beauty of the Baader T-2 System!Please Note: The Baader T-2 Prism Diagonal has a clear aperture of 32mm. It incorporates standard T-2 threads at the input and output faces and is provided as a basic component, without any input or output fittings.

Baader Planetarium 1.25" Contrast Booster Telescope Filter - FCB-1

Much more than a simple minus-violet filter. Based on the popular Baader Moon &and Skyglow filter, the Baader 1.25" Contrast-Booster takes contrast enhancement and skyglow reduction to the maximum level possible from a filter. Not only does this filter deliver a significant enhancement of planetary and lunar contrasts, but it is designed to also totally eliminate the damaging blue defocused haze present in achromatic refractors. Gone are the annoying blue halo and obscuring haze that surrounds and smear resolution and contrast. Subtle contrasts and colors are boosted while displaying the full resolution your scope is capable of.The Contrast-Booster combines a special proprietary melt of Neodymium glass with a carefully designed 23 layer dielectric long-pass blocker on one face and a 7-layer ultra-low antireflection coating on the other face. By aggressively filtering out the defocused blue wavelengths, a light yellow tint is imparted to objects (noticeably less than a typical yellow filter). The special coatings enable over 95% transmission across key portions of the visible spectrum. This results in a filter that retains the colors and color contrasts in tough subjects like Jupiter, without excessive image dimming. Cloud bands retain their ruddy red hues but now become more striking in contrast. The Great Red Spot finally becomes easier. Planets and Lunarscapes are set against a jet black sky. The Contrast-Booster is a must for Solar observing (with Baader Astro Solar).As many users have found, this is the ideal filter for Mars! The views of Mars with all telescopes (including reflectors and apochromats) benefit from the RGB filtration plus blue blocking.Combined with the Baader UV-IR-Cut Filter, the Contrast-Booster makes the ideal filter set for digital imaging. Rather than add the cost of additional IR filtration (only needed for digital imaging), the Baader Contrast Booster has been optimized for visual use. Digital images can simply add our Baader UV-IR-Cut Filter when needed. The true 1/4 wave fine optically polished surfaces guarantee the sharpness and contrast of the image. Filters are available in both 1¼ and 2" sizes.The base substrate is a special custom melt of Neodymium-doped glass, designed for specific transmission characteristics, and made only for Baader Planetarium. In addition to its unique spectral characteristics, the Contrast-Booster offers Baader's hallmark optical and mechanical features that set it apart and result in the best possible image sharpness, contrast, and real-world durability.

Baader Planetarium 1.25" Dark Blue Eyepiece Filter - 435 nm Bandpass - FCFDB-1

Baader Planetarium 435 nm Bandpass Dark Blue Eyepiece Filter - 1.25"Freedom from Ghost images, even when stacked. To avoid wedge errors, striae-free substrates are polished parallel to 30 seconds. First-class 7-layer hard multi-coatings on each face have 0.25% residual reflections. Baader filters are unique in this way as no other colored filter includes anti-reflection multicoatings. In addition, these coatings differ depending on the filter so that the coating performance matches the filter curve of each color. This increases transmission while decreasing reflections.Extremely High Transmissions result in maximum contrast and isolation of planetary details, even with smaller telescopes. Efficiencies of the three longpass filters (Red, Orange, and Yellow) peaks at 98%, and efficiencies of the three bandpass filters (Green, Blue, Dark Blue) achieve 70%. Carefully designed spectral characteristics. Filters may be stacked without image degradation or ghosting, in order to provide even narrower passbands. Or, combine with any of the other Baader filters for interesting possibilities.No reduction in sharpness, even at high magnifications or when using the filter far ahead of the focal plane (ie, digital imaging, or in front of a diagonal or binoviewer).

Baader Planetarium 1.25" IR Pass (685 nm) FilterBaader Planetarium's 1.25" IR-Pass filter blocks wavelengths below 670 nm for increased contrast and image sharpness. By combining a luminance image taken with the IR-Pass filter, along with RGB frames, overall image sharpness is significantly enhanced. Some of the world's best amateur planetary images have been taken with this technique.The IR-Pass filter shares the same outstanding features as all the other Baader filters. High optical quality, Striae-free substrate and high-efficiency multi-coatings result in the sharpest and highest contrast image possible.

Baader Planetarium 1.25" Moon &and Skyglow Telescope Filter - FMS-1

The Baader 1.25" Planetarium Moon &and Skyglow (Neodymium) filter brings an entirely unique approach to contrast enhancement and light pollution reduction. Based on earlier research at Carl Zeiss, Baader has developed a new filter that uses Neodymium glass which filters out a few specific wavelengths from streetlights as well as skyglow from the Moon. The unique spectral characteristics of Neodymium also boost color contrasts by isolating the Red, Green, and Blue regions (so-called RGB enhancement). The result is a filter that leaves natural colors intact but enhanced.Lunar and Planetary views are improved in all scopes, reflectors, refractors (APO or Achro). Jupiter's Great Red Spot and ruddy hues of the bands are noticeably enhanced. The Background sky is darkened, and subtle details improved. The filter's high efficiency preserves image brightness, and many Galaxies, Nebulae and Globular Star Clusters are improved due to the reduction of skyglow from artificial lighting.The high quality of Baader Planetarium filters permits stacking with no image degradation. Achromat owners will find the combination of Moon &and Skyglow and the new Fringe Killer filter to be ideal for planetary viewing. The high light throughput and natural coloration will make achromats perform more like an apochromat.The filter substrate is a special custom melt of Neodymium-doped glass, designed for specific transmission characteristics, and made only for Baader Planetarium. In addition to its unique spectral characteristics, the Baader Moon &and Skyglow filter delivers the best possible image sharpness, contrast, and real-world durability.

Baader Planetarium 1.25" ND 0.6 Neutral Density Filter - FND0-1

Baader 1.25" Neutral Density ND 0.6 FilterOver the years Baader Planetarium has developed the latest coating technologies. The 1.25", Multicoated Neutral Density Filter is unlike any other competing filter out there, while also remaining reasonable in price. This filter has an ND 0.6 Multicoated density, housed in a 1.25" filter cell. Use this Baader Filter to attenuate the light from bright objects for enhanced views of celestial objects

Baader Planetarium 1.25" O-III Nebula Telescope Filter - FOII-1

Delivers the absolute highest contrast views of many diffuse and planetary nebula. For many objects, the Baader 1.25" O-III Nebula Filter reveals a level of intricate detail that rivals the best deep sky photographs. Our favorite filter for the majority of nebula, especially The Veil, Lagoon (M8), Swan (M17), Ring (M57) and Dumbell (M29). With a large scope, you can even view the famous 'Pillars of Creation' in M16 (Eagle). The Baader O-III perfectly isolates the two doubly ionized oxygen lines (496 and 501nm), through a very sharp and narrow bandpass (8.2 nm wide!, the narrowest of any O-III filter). Unlike other O-III filters, the Baader O-III completely blocks longer and shorter wavelengths (ever wonder why some O-III filters appear RED, instead of the correct 500 nm Teal color). The result is the highest contrast achievable in an O-III filter. The O-III benefits from the precision fineoptically polished flat substrate, and advanced DWDM plasma assisted coatings. As a result, the Baader O-III will not degrade image sharpness or impart double images. To prevent deterioration from cleaning or exposure to moisture, some other filters even resort to sandwiching their delicate coatings between two layers of filter glass, resulting in potential blurred or double images. Contrary to myth, nebula filters are often useful at high magnifications, where image quality counts. Baader O-III filters can take high magnifications, and stars retain their pinpoint sharpness, even if the filter is used far ahead of the image plane (ie, for imaging use, or ahead of a star diagonal or binoviewer). Combine with our UV/IR filter for the ultimate in O-III deep sky imaging.

Baader Planetarium 1.25" Orange Eyepiece Filter - 570 nm Longpass - FCFO-1

Baader 1.25" Orange 570 nm Longpass FilterFreedom from Ghost images, even when stacked. To avoid wedge errors, striae-free substrates are polished parallel to 30 seconds. First-class 7-layer hard multi-coatings on each face have 0.25% residual reflections. Baader filters are unique in this way as no other colored filter includes anti-reflection multicoatings. In addition, these coatings differ depending on the filter so that the coating performance matches the filter curve of each color. This increases transmission while decreasing reflections.Extremely High Transmissions deliver maximum contrast to highlight planetary details, even when smaller telescopes are being employed. The three Baader longpass filters (Red, Orange, and Yellow) have peak efficiencies of 98%, while the three Baader bandpass filters (Green, Blue, and Dark Blue) top out at 70%.Carefully designed spectral characteristics. Filters may be stacked without image degradation or ghosting, in order to provide even narrower passbands. Or, combine with any of the other Baader filters for interesting possibilities.No reduction in sharpness, even at high magnifications or when using the filter far ahead of the focal plane (ie, digital imaging, or in front of a diagonal or binoviewer).

Baader Planetarium 1.25" Solar Continuum Telescope Filter - FSOL-1

The new Baader 1.25" Solar Continuum filter is designed to enhance the visibility of solar granulation and sunspot details. By transmitting a specific spectral region around 540nm, free of emission and absorption lines, the Solar Continuum filter is able to boost contrast and reduce the effects of atmospheric turbulence. With the Solar Continuum filter in place, images snap to focus and granulation becomes regularly visible. Details at the limit of visibility become easier to hold, and image motion is reduced.The Solar Continuum filter works well in all types of telescopes, for both visual and imaging. Users of SCTs and achromatic refractors will find it particularly beneficial, as it completely excludes the red and blue wavelengths and centers on the peak visual wavelengths where the telescope optics are sharpest and free from chromatic aberrations. For digital imaging, we also recommend the Continuum filter be combined with our UV/IR Cut Filter (to completely cut the defocused far infrared wavelengths).The Solar Continuum filter also makes the perfect star test filter. Its narrow bandpass and complete blockage of longer and shorter wavelengths make it superior to standard green colored filters for testing refractors at their center design wavelength (and peak visual wavelength). With this filter, more accurate appraisals of optical quality can be made without the effects of spherochromatism or secondary color error. Due to the narrow 10nm bandpass, star testing through the Solar Continuum filter will require a bright test star.As with all Baader Planetarium Filters, the Solar Continuum possesses all the trademark Baader filter qualities. Optical, physical, and mechanical quality are superb.Please Note: for safe use, the Solar Continuum filter must be used in conjunction with a primary solar filter (ie, Herschel Wedge Prism, or Baader AstroSolar Film). It must be placed after the primary filter and cannot be used alone, or permanent eye and equipment damage will result.

Baader Planetarium 1.25" UHC-S Nebula Telescope Filter - FUHC-1

The Baader Planetarium 1.25" UHC-S Nebula filter excels at delivering a high-contrast and natural view of emission nebula without excessive dimming and loss of background star fields. It's the perfect filter for viewing emission nebula from light polluted skies, or for boosting the contrast of nebula from dark sky sites. The advanced technology coatings enable the filter to achieve an outstanding transmission of over 97% across the entire passband, with total blockage of prominent light pollution lines. This translates to maximum image brightness and contrast. Owners of smaller, 4"-10" telescopes will especially appreciate the high efficiency, and larger scope users will love the rich star fields and detailed subtle nebular shadings that are left intact.The Baader UHC-S manages to improve on the contrast of the typical broadband or so-called "Deep Sky" filters. Sky background is darker, and contrast of emission nebulae are noticeably improved. Most other "UHC" filters tend to excessively darken the sky and star fields, leaving the nebulae looking artificial and flat, set against an empty background. The high transmission, sharp cutoffs, and more moderate 60nm passband of the Baader UHC-S filter retain a more natural view, yet significantly boosts overall contrast. Imagers will appreciate the broader passband and inclusion of an extremely efficient H-Alpha passband (>99% @656nm), as well as the extreme optical quality.At the heart of the Baader UHC-S filters are their special fine optical substrate polishing process and advanced coating design. The result is a filter that imparts no image degradation, unlike other filters. To prevent deterioration from cleaning or exposure to moisture, some other filters even resort to sandwiching their delicate coatings between two layers of filter glass, resulting in potential blurred or double images. The combination of hardened coatings and fine optical substrate of the Baader UHC-S avoids this image degradation. A common misperception is that deep sky viewing is limited to low powers, and image resolution is not as important as in planetary observation. In reality, high magnifications are very common and useful in studying fine details, particularly for the brighter diffuse and planetary nebulae. Baader UHC-S filters can take high magnifications, and stars retain their pinpoint sharpness, even if the filter is used far ahead of the image plane (ie, for imaging use, or ahead of a star diagonal or binoviewer). Baader filters fulfill the requirements of an ideal filter to perform their filtration at highest efficiency without any other detectable effect on the image.

Baader Planetarium 1.25" UV-IR-Cut Telescope Filter - FUVIR-1

Baader Planetarium has introduced the world's finest 1.25" UV/IR cut filter. This filter is a must for all digital imaging with digital cameras, CCD cameras, and modified webcams. It's also useful for protecting valuable H-Alpha filters from heat stress and damaging IR (Daystar, etc). Due to their extremely high optical quality, these filters may be stacked and used far in front of the focal plane (necessary for imaging uses). Like the Baader Planetarium Contrast-Booster, the UV-IR-Cut filter uses the very latest coating technology to deliver the finest filtration quality and lifetime durability.Features:Unmatched 98% Average Transmission! Freedom from ghost images (very low reflection multi-coating, Striae-free, and plane-parallel substrate).Extremely Sharp Cutoff at 690nm (leaves all the visible red, including the important 656nm H-alpha emission line).Sharp cutoff below 400nm. Eliminates violet halos around bright stars (more effectively than simpler so-called Minus Violet photographic filters).True optical quality glass substrate and coatings. Why spend all your money on a quality primary optic, only to place a lower grade filter optic in the path?Combine with any of the other Baader filters to deliver the sharpest images possible."Got the UV-IR-cut filter. Mounted it internally inside a 400mm lens that I glued to a cheap 3.2 MP camera WORKS GREAT!! Better than the hot mirror supplied with camera more red channel more light - higher shutter speed. At least one extra stop." Luke Gale

The eyepiece holder uses dual nickel plated clamp screws for maximum convenience and security, and incorporates a captive spring bronze lock ring to prevent any possibility of damage to your eyepieces. The internal surfaces are all fully sharp V-threaded and blackened to eliminate stray light reflections. Surfaces are finely machined and satin anodized for function and appearance.One of the distinguishing features of the VIP Modular Barlow is its construction from multiple interchangeable parts. The T-2/1 1/4" nosepiece barrel is threaded for standard 1 1/4" filters, and the 2"/1 1/4" reducer (#15) is threaded to accept 2" filters. The structural modules of this Baader 1.25" VIP Barlow interconnect using standard T-2 (42 mm) threads.

Baader Planetarium 1.25" Yellow Eyepiece Filter - 495 nm Longpass - FCFY-1

Baader Planetarium 495 nm Bandpass Yellow Eyepiece Filter - 1.25"Freedom from Ghost images, even when stacked. To avoid wedge errors, striae-free substrates are polished parallel to 30 seconds. First-class 7-layer hard multi-coatings on each face have 0.25% residual reflections. Baader filters are unique in this way as no other colored filter includes anti-reflection multicoatings. In addition, these coatings differ depending on the filter so that the coating performance matches the filter curve of each color. This increases transmission while decreasing reflections.Extremely High Transmissions provide maximum contrast to bring out planetary details, even when smaller telescopes are used. The three Baader longpass filters (Red, Orange, and Yellow) have peak efficiencies of 98%, while the three Baader bandpass filters (Green, Blue, and Dark Blue) top out at 70%.Carefully designed spectral characteristics. Filters may be stacked without image degradation or ghosting, in order to provide even narrower passbands. Or, combine with any of the other Baader filters for interesting possibilities.No reduction in sharpness, even at high magnifications or when using the filter far ahead of the focal plane (ie, digital imaging, or in front of a diagonal or binoviewer).

Baader Hyperion Multi-Purpose 68 Degree Eyepieces - Great for visual use All Baader Hyperion eyepieces have an optimal 68 degree apparent field of view, the largest accessible to the stationary human eye. The entire field remains visible despite slight involuntary motions of an observer’s head.The annoying "kidney bean effect", the bane of many ultra wide-field eyepiece designs, is completely absent in the Baader Hyperion.Eight lens elements in five groups provide outstanding sharpness and color correction over the entire field.The Baader Hyperion 10mm eyepiece has 20mm of comfortable eye relief.No vignetting or falloff of illumination near the edge of the field.The use of high-index glass results in minimal distortion and astigmatism.The Baader Hyperion has unsurpassed color fidelity. Many eyepieces that employ cheaper glasses or inferior designs impart a yellow or blue cast to the image. With Hyperion eyepieces white stays white!The most advanced anti-reflection multi-coatings are employed on all ten air-to=glass surfaces for maximum light throughput and brilliant images. All coatings are carefully matched to the index of refraction for each of the different glass substrates used.The painstaking design and execution of baffling has all but eliminated troublesome stray light and ghost reflections. Under all conditions of illumination, the interior of a Hyperion eyepiece will appear jet black, testimony to the virtual elimination of stray light.The Hyperion has the shortest field stop position of all wide field eyepieces known.Specifically designed for binocular viewing. Ideal for use with accessory binocular viewers thanks to a tight barrel diameter (58 millimeters with the removable neoprene rubber grip ring, 56 millimeters with the grip ring removed) that permits interpupillary distance settings of as little as 56 millimeters.Each Hyperion eyepiece in the series is actually two eyepieces in one! A much longer focal length lens can be created by unscrewing the forward 1.25-inch diameter portion of barrel that houses the negative achromat lens group. Color correction remains excellent, and the field curvature that results is no greater than in a decent specimen of the 6-element Erfle design. Removing the negative lens group exposes an M48 female thread so that large-format light pollution and nebular filters can be employed.Thanks to the short 1.25 chrome sleeve of 0.94”, all Hyperion’s are principally compatible with spotting scopes, including high-end units by Leica, Swarovski, and Zeiss.The perfect eyepiece for afocal projection imaging The digital camera threads S54 and M43 x 0.75 have been incorporated into the Hyperion eyepiece for compatibility with the Baader Series 54 digital T-rings. With a Series 54 t-ring installed on the Hyperion, you can attach almost any digital and videocamera without vignetting. These threads are protected by caps when not in use.The vast majority of large digital cameras and camcorders of recent vintage feature an internal zoom lens with a fixed front lens and standard filter threads.The robust construction of Hyperion eyepieces is capable of directly supporting heavy video and film cameras weighing up to 6.6 lb.Hyperion eyepieces are also ideal for use with so-called clamping-style universal digital camera holders, and will precisely support cameras squarely with respect to the optical axis, due to their straight forward cylindrical-shaped outer body.With or without the removable negative lens group, the Hyperion eyepiece is an incredibly sharp projection system.In combination with a short-focus objective as small as 60mm, the same afocal imaging configuration can be employed in industry for monitoring hazardous operations like plasma welding from a safe distance.

Not only does this filter deliver a significant enhancement of planetary and lunar contrasts, but it is designed to also totally eliminate the damaging blue defocused haze present in achromatic refractors. Gone are the annoying blue halo and obscuring haze that surrounds and smear resolution and contrast. Subtle contrasts and colors are boosted while displaying the full resolution your scope is capable of.The Contrast-Booster combines a special proprietary melt of Neodymium glass with a carefully designed 23 layer dielectric long-pass blocker on one face and a 7-layer ultra-low antireflection coating on the other face. By aggressively filtering out the defocused blue wavelengths, a light yellow tint is imparted to objects (noticeably less than a typical yellow filter). The special coatings enable over 95% transmission across key portions of the visible spectrum. This results in a filter that retains the colors and color contrasts in tough subjects like Jupiter, without excessive image dimming. Cloud bands retain their ruddy red hues but now become more striking in contrast. The Great Red Spot finally becomes easier. Planets and Lunarscapes are set against a jet black sky. The Contrast-Booster is a must for Solar observing (with Baader Astro Solar).As many users have found, this is the ideal filter for Mars! The views of Mars with all telescopes (including reflectors and apochromats) benefit from the RGB filtration plus blue blocking.Combined with the Baader UV-IR-Cut Filter, the Contrast-Booster makes the ideal filter set for digital imaging. Rather than add the cost of additional IR filtration (only needed for digital imaging), the Baader Contrast Booster has been optimized for visual use. Digital images can simply add our Baader UV-IR-Cut Filter when needed. The true 1/4 wave fine optically polished surfaces guarantee the sharpness and contrast of the image. Filters are available in both 1¼ and 2" sizes.The base substrate is a special custom melt of Neodymium-doped glass, designed for specific transmission characteristics, and made only for Baader Planetarium. In addition to its unique spectral characteristics, the Contrast-Booster offers Baader's hallmark optical and mechanical features that set it apart and result in the best possible image sharpness, contrast, and real-world durability.

Baader Planetarium 2" Deluxe ClickLock Eyepiece Extension - EXT-CLSC

Baader 2" Deluxe ClickLock Eyepiece ExtensionThis Baader ClickLock Extension Clamp is a precision eyepiece holder that allows for the insertion of eyepieces or accessories at any point in the Baader Astro T-2 System™, or for improving the standard holder that came with your telescope. The ClickLock represents a better eyepiece holder concept. After you've tried one, you won't want to step back to simple set screw or even captive brass clamp rings again! All it takes is a gentle twist for two special non-marring cam rollers to connect with the eyepiece and securely lock it in place in the holder. That eyepiece wobble frequently experienced in single screw clamps or lock-ring style holders is guaranteed to be eliminated thanks to 3-point clamp action. In addition, the absence of a protruding lock screw takes care of the major inconvenience of having to continuously re-position your nose around an awkwardly positioned screw.The eyepiece holder is precisely machined to fit with a minimum of slop, resulting in a close, accurate fit that keeps your eyepiece properly centered on the optical axis. The long contact length of the cam rollers also makes this holder compatible with all grooved eyepiece barrels by bridging the groove. On the front (input) side, the eyepiece clamp has an internal T-2 thread to mate it to the other components of the T-2 system. On the output side, Baader has added two additional unique and useful features. The top of the holder is actually an adjustable micro-focusing collar, with 6.5 mm of travel. It allows you to precisely vary and set the overall clamp height to allow fine adjustment of focus or height for matching other accessories. Furthermore, this ring is removable, which exposes an external T-2 thread. By coupling extension tubes, you can use the Click-Lock as an afocal projection system (using eyepieces with outside diameters of 37mm maximum).The Baader Click-Lock Eyepiece Clamp makes a superior replacement for the stock eyepiece holders supplied with popular telescopes.The Click-Lock Eyepiece Clamp is also a key component for a number of common Astro T-2 System configurations, such as the Precision Amici Diagonal, and as a parfocal eyepiece holder for CCD focusing with the Alan Gee Mark II Telecompressor.

Baader Planetarium 2" Green Eyepiece Filter - 500 nm Bandpass - FCFG-2

Freedom from Ghost images, even when stacked. Striae-free substrates are polished parallel to 30 seconds to prevent wedge errors. Both faces feature the finest 7-layer hard multi-coatings with 0.25% residual reflections. No other colored filter on the market incorporates anti-reflection multi-coatings. Furthermore, these coatings vary depending on the filter in order to couple the coating performance with the filter curve of each color. This maximizes transmission while minimizing reflections.Extremely High Transmissions deliver maximum contrast to highlight planetary details, even when smaller telescopes are being employed. The three Baader longpass filters (Red, Orange, and Yellow) have peak efficiencies of 98%, while the three Baader bandpass filters (Green, Blue, and Dark Blue) top out at 70%.Carefully designed spectral characteristics. Baader 2" color filters are stackable without image deterioration or ghosting, for even more narrow passbands. You can also combine them with other Baader filters for many potential possibilities.No reduction in sharpness, even at high magnifications or when using the filter far ahead of the focal plane (ie, digital imaging, or in front of a diagonal or binoviewer).

Baader Planetarium 2" IR-Pass Telescope Filter - FIRP-2

Baader Planetarium delivers the latest tool in the planetary imager's bag of tricks. The Baader 2" IR-Pass filter blocks wavelengths below 670 nm. At these longer wavelengths, planetary images are less disturbed by wavefront distortions in the atmosphere (seeing). By combining a luminance image taken with the IR-Pass filter, along with RGB frames, overall image sharpness is significantly enhanced. Some of the world's best amateur planetary images have been taken with this technique.The IR-Pass filter shares the same outstanding features as all the other Baader filters. High optical quality, Striae-free substrate and high-efficiency multi-coatings result in the sharpest and highest contrast image possible.

Baader Planetarium 2" Mark III Multi Purpose Coma Corrector - MPCC

Baader 2" Multi Purpose Coma Corrector - MK IIIThe Baader Planetarium Multi Purpose Coma Corrector has been optimized for Newtonians with focal ratios from f/4 to f/6, and will deliver 12 micron stars across a full 35 mm frame size. Independent optical laboratory tests (by ITE) have confirmed that the MPCC is the sharpest wide-field coma corrector available for imaging, and provides the best edge of field illumination. Visual users have reported great results even down to f/3.7. The optics are anti-reflection coated with the finest 7 layer multi-coatings available. The MPCC modular design lets you purchase only the parts you need. For imaging with DSLRs, only the MPCC is required. For visual, the MPCC can be configured with any of Baader's eyepiece holders or directly coupled to 2" eyepieces using Astro T-2 System components.Dob users with f/3.7 - f/5 scopes have discovered the unique benefits of the 2" Multi Purpose Coma Corrector - MK III versus other coma correctors. The MPCC can be inexpensively configured for visual use with 1.25" and 2" eyepieces.The 2" Multi Purpose Coma Corrector - MK III is the ideal match for today's Digital SLRs. Owners of these new cameras find them to be ideally mated with today's fast f/4-f/5 Newtonians required to keep exposures short. The MPCC enables these users to fully correct their scopes and produce superb pinpoint color deep sky images without the complexity of more expensive CCD cameras.The MPCC does NOT extend the focal ratio (so, your images will be shot at the full speed of your telescope). The MPCC inserts into 2" focusers and has external T-threads on the output side (and is also threaded for standard 2"/48 mm filters). Simply attach any 35 mm film or digital SLR to the MPCC, with T-adapters. Users of CCD cameras can attach in the same way through the use of Baader Astro T-2 System components.The MPCC is designed for a nominal 55 mm distance from the mounting flange to the image plane. It also extends the focus point by approximately 10 mm, so no additional back-focus is needed to use the MPCC (of course, this assumes your camera will already reach focus in your telescope, without the MPCC). The latest version of the MPCC now includes a removable stop flange, which when removed exposes an M48 external thread, which enables the MPCC to be directly coupled to 2" eyepieces and inserted fully inside 2" focusers.

Baader Planetarium 2" Moon &and Skyglow Telescope Filter - FMS-2

The Baader 2" Planetarium Moon &and Skyglow (Neodymium) filter brings an entirely unique approach to contrast enhancement and light pollution reduction. Based on earlier research at Carl Zeiss, Baader has developed a new filter that uses Neodymium glass which filters out a few specific wavelengths from streetlights as well as skyglow from the Moon. The unique spectral characteristics of Neodymium also boost color contrasts by isolating the Red, Green, and Blue regions (so-called RGB enhancement). The result is a filter that leaves natural colors intact but enhanced.Lunar and Planetary views are improved in all scopes, reflectors, refractors (APO or Achro). Jupiter's Great Red Spot and ruddy hues of the bands are noticeably enhanced. The Background sky is darkened, and subtle details improved. The filter's high efficiency preserves image brightness, and many Galaxies, Nebulae and Globular Star Clusters are improved due to the reduction of skyglow from artificial lighting.The high quality of Baader Planetarium filters permits stacking with no image degradation. Achromat owners will find the combination of Moon &and Skyglow and the new Fringe Killer filter to be ideal for planetary viewing. The high light throughput and natural coloration will make achromats perform more like an apochromat.The filter substrate is a special custom melt of Neodymium-doped glass, designed for specific transmission characteristics, and made only for Baader Planetarium. In addition to its unique spectral characteristics, the Baader Moon &and Skyglow filter delivers the best possible image sharpness, contrast, and real-world durability.

Baader Planetarium 2" O-III Nebula Telescope Filter - FOIII-2

Delivers the absolute highest contrast views of many diffuse and planetary nebula. For many objects, the Baader 2" O-III Nebula Filter reveals a level of intricate detail that rivals the best deep sky photographs. Our favorite filter for the majority of nebula, especially The Veil, Lagoon (M8), Swan (M17), Ring (M57) and Dumbell (M29). With a large scope, you can even view the famous 'Pillars of Creation' in M16 (Eagle). The Baader O-III perfectly isolates the two doubly ionized oxygen lines (496 and 501nm), through a very sharp and narrow bandpass (8.2 nm wide!, the narrowest of any O-III filter). Unlike other O-III filters, the Baader O-III completely blocks longer and shorter wavelengths (ever wonder why some O-III filters appear RED, instead of the correct 500 nm Teal color). The result is the highest contrast achievable in an O-III filter. The O-III benefits from the precision fineoptically polished flat substrate, and advanced DWDM plasma assisted coatings. As a result, the Baader O-III will not degrade image sharpness or impart double images. To prevent deterioration from cleaning or exposure to moisture, some other filters even resort to sandwiching their delicate coatings between two layers of filter glass, resulting in potential blurred or double images. Contrary to myth, nebula filters are often useful at high magnifications, where image quality counts. Baader O-III filters can take high magnifications, and stars retain their pinpoint sharpness, even if the filter is used far ahead of the image plane (ie, for imaging use, or ahead of a star diagonal or binoviewer). Combine with our UV/IR filter for the ultimate in O-III deep sky imaging.

Baader Planetarium 2" Orange Eyepiece Filter - 570 nm Longpass - FCFO-2

Baader Planetarium 2" Solar Continuum Telescope Filter - FSOL-2

The new Baader 2" Solar Continuum filter is designed to enhance the visibility of solar granulation and sunspot details. By transmitting a specific spectral region around 540nm, free of emission and absorption lines, the Solar Continuum filter is able to boost contrast and reduce the effects of atmospheric turbulence. With the Solar Continuum filter in place, images snap to focus and granulation becomes regularly visible. Details at the limit of visibility become easier to hold, and image motion is reduced.The Solar Continuum filter works well in all types of telescopes, for both visual and imaging. Users of SCTs and achromatic refractors will find it particularly beneficial, as it completely excludes the red and blue wavelengths and centers on the peak visual wavelengths where the telescope optics are sharpest and free from chromatic aberrations. For digital imaging, we also recommend the Continuum filter be combined with our UV/IR Cut Filter (to completely cut the defocused far infrared wavelengths).The Solar Continuum filter also makes the perfect star test filter. Its narrow bandpass and complete blockage of longer and shorter wavelengths make it superior to standard green colored filters for testing refractors at their center design wavelength (and peak visual wavelength). With this filter, more accurate appraisals of optical quality can be made without the effects of spherochromatism or secondary color error. Due to the narrow 10nm bandpass, star testing through the Solar Continuum filter will require a bright test star.As with all Baader Planetarium Filters, the Solar Continuum possesses all the trademark Baader filter qualities. Optical, physical, and mechanical quality are superb.Please Note: for safe use, the Solar Continuum filter must be used in conjunction with a primary solar filter (ie, Herschel Wedge Prism, or Baader AstroSolar Film). It must be placed after the primary filter and cannot be used alone, or permanent eye and equipment damage will result.

Baader Planetarium 2" Standard Eyepiece Extension - EXT-2

Baader 2" Standard Eyepiece ExtensionThis Baader 2" Standard Eyepiece Extension consists of two parts, a T2-17 2" Deluxe Clamping Eyepiece holder, and a 2" barrel. The T2-17 contains a captive bronze compression ring, as well as large stainless steel thumbscrews to avoid causing damage to your eyepiece or accessory. The inclusion of the 2-point screws provide a 3-point attachment to completely inhibit any wobble. While some motion is still enabled by most single clamp screws, having the 2-point screws restrict such motion to a bare minimum. Additionally, users who are physically unable to firmly grasp the thumbscrew can now use the two screws to double the locking force. The holder is precisely machined to fit your eyepieces with slop kept to a minimum for a tight, accurate fit that maintains correct centering on the optical axis. The holder features 2" internal thread identical to the SCT rear thread. This lets the holder be threaded directly into Schmidt-Cassegrains for the widest views possible.

Baader Planetarium 2" UHC-S Nebula Telescope Filter - FUHC-2

The Baader Planetarium 2" UHC-S Nebula filter excels at delivering a high-contrast and natural view of emission nebula without excessive dimming and loss of background star fields. It's the perfect filter for viewing emission nebula from light polluted skies, or for boosting the contrast of nebula from dark sky sites. The advanced technology coatings enable the filter to achieve an outstanding transmission of over 97% across the entire passband, with total blockage of prominent light pollution lines. This translates to maximum image brightness and contrast. Owners of smaller, 4"-10" telescopes will especially appreciate the high efficiency, and larger scope users will love the rich star fields and detailed subtle nebular shadings that are left intact.The Baader UHC-S manages to improve on the contrast of the typical broadband or so-called "Deep Sky" filters. Sky background is darker, and contrast of emission nebulae are noticeably improved. Most other "UHC" filters tend to excessively darken the sky and star fields, leaving the nebulae looking artificial and flat, set against an empty background. The high transmission, sharp cutoffs, and more moderate 60nm passband of the Baader UHC-S filter retain a more natural view, yet significantly boosts overall contrast. Imagers will appreciate the broader passband and inclusion of an extremely efficient H-Alpha passband (>99% @656nm), as well as the extreme optical quality.At the heart of the Baader UHC-S filters are their special fine optical substrate polishing process and advanced coating design. The result is a filter that imparts no image degradation, unlike other filters. To prevent deterioration from cleaning or exposure to moisture, some other filters even resort to sandwiching their delicate coatings between two layers of filter glass, resulting in potential blurred or double images. The combination of hardened coatings and fine optical substrate of the Baader UHC-S avoids this image degradation. A common misperception is that deep sky viewing is limited to low powers, and image resolution is not as important as in planetary observation. In reality, high magnifications are very common and useful in studying fine details, particularly for the brighter diffuse and planetary nebulae. Baader UHC-S filters can take high magnifications, and stars retain their pinpoint sharpness, even if the filter is used far ahead of the image plane (ie, for imaging use, or ahead of a star diagonal or binoviewer). Baader filters fulfill the requirements of an ideal filter to perform their filtration at highest efficiency without any other detectable effect on the image.

Baader Planetarium 2" UV-IR-Cut Telescope Filter - FUVIR-2

Baader Planetarium has introduced the world's finest 2" UV/IR cut filter. This filter is a must for all digital imaging with digital cameras, CCD cameras, and modified webcams. It's also useful for protecting valuable H-Alpha filters from heat stress and damaging IR (Daystar, etc). Due to their extremely high optical quality, these filters may be stacked and used far in front of the focal plane (necessary for imaging uses). Like the Baader Planetarium Contrast-Booster, the UV-IR-Cut filter uses the very latest coating technology to deliver the finest filtration quality and lifetime durability.Features:Unmatched 98% Average Transmission! Freedom from ghost images (very low reflection multi-coating, Striae-free, and plane-parallel substrate).Extremely Sharp Cutoff at 690nm (leaves all the visible red, including the important 656nm H-alpha emission line).Sharp cutoff below 400nm. Eliminates violet halos around bright stars (more effectively than simpler so-called Minus Violet photographic filters).True optical quality glass substrate and coatings. Why spend all your money on a quality primary optic, only to place a lower grade filter optic in the path?Combine with any of the other Baader filters to deliver the sharpest images possible."Got the UV-IR-cut filter. Mounted it internally inside a 400mm lens that I glued to a cheap 3.2 MP camera WORKS GREAT!! Better than the hot mirror supplied with camera more red channel more light - higher shutter speed. At least one extra stop." Luke Gale

The substrates of this Baader 2" filter are free of striae and polished parallel to 30 seconds in order to avoid wedge errors. It features the finest hard 7-layer multi-coatings on each face with 0.25% residual reflections. Baader filters are special in this regard as all competing filters are without anti-reflection multi-coatings. Futhermore, the coatings differ for each filter so that they match the coating performance to each color's filter curve to increase transmission while decreasing reflections.Extremely High Transmissions provide maximum contrast to bring out planetary details, even when smaller telescopes are used. The three Baader longpass filters (Red, Orange, and Yellow) have peak efficiencies of 98%, while the three Baader bandpass filters (Green, Blue, and Dark Blue) top out at 70%.Carefully designed spectral characteristics. In order to deliver even narrower passbands, these color filters from Baader can be stacked without ghosting or image degradation. Additionally, they can combine with other Baader filters to enable many interesting contingencies.No reduction in sharpness, even at high magnifications or when using the filter far ahead of the focal plane (ie, digital imaging, or in front of a diagonal or binoviewer).

Baader Planetarium 21mm Hyperion Telescope Eyepiece - HYP-21

Baader Planetarium 21mm Hyperion Telescope Eyepiece This Baader Planetarium 21mm Hyperion Eyepiece is more than just a pretty face! With a 68 degree field of view, coatings that rival eyepieces costing hundreds of dollars more, and great eye relief, the Baader Hyperion's are the perfect visual eyepiece, however, their innovative auto-locking 2 inch sleeve supports heavy cameras for afocal projection photography with the appropriate Hyperion T-ring. Baader Hyperion Multi-Purpose 68 Degree Eyepieces - Great for visual use All Baader Hyperion eyepieces have an optimal 68 degree apparent field of view, the largest accessible to the stationary human eye. The entire field remains visible despite slight involuntary motions of an observer’s head.The annoying "kidney bean effect", the bane of many ultra wide-field eyepiece designs, is completely absent in the Baader Hyperion.Eight lens elements in five groups provide outstanding sharpness and color correction over the entire field.The Baader 21mm Hyperion eyepiece has 20mm of comfortable eye relief.No vignetting or falloff of illumination near the edge of the field.The use of high-index glass results in minimal distortion and astigmatism.The Baader Hyperion has unsurpassed color fidelity. Many eyepieces that employ cheaper glasses or inferior designs impart a yellow or blue cast to the image. With Hyperion eyepieces white stays white!The most advanced anti-reflection multi-coatings are employed on all ten air-to=glass surfaces for maximum light throughput and brilliant images. All coatings are carefully matched to the index of refraction for each of the different glass substrates used.The painstaking design and execution of baffling has all but eliminated troublesome stray light and ghost reflections. Under all conditions of illumination, the interior of a Hyperion eyepiece will appear jet black, testimony to the virtual elimination of stray light.The Hyperion has the shortest field stop position of all wide field eyepieces known.Specifically designed for binocular viewing. Ideal for use with accessory binocular viewers thanks to a tight barrel diameter (58 millimeters with the removable neoprene rubber grip ring, 56 millimeters with the grip ring removed) that permits interpupillary distance settings of as little as 56 millimeters.Each Hyperion eyepiece in the series is actually two eyepieces in one! A much longer focal length lens can be created by unscrewing the forward 1.25-inch diameter portion of barrel that houses the negative achromat lens group. Color correction remains excellent, and the field curvature that results is no greater than in a decent specimen of the 6-element Erfle design. Removing the negative lens group exposes an M48 female thread so that large-format light pollution and nebular filters can be employed.Thanks to the short 1.25 chrome sleeve of 0.94”, all Hyperion’s are principally compatible with spotting scopes, including high-end units by Leica, Swarovski, and Zeiss. The perfect eyepiece for afocal projection imaging The digital camera threads S54 and M43 x 0.75 have been incorporated into the Hyperion eyepiece for compatibility with the Baader Series 54 digital T-rings. With a Series 54 t-ring installed on the Hyperion, you can attach almost any digital and videocamera without vignetting. These threads are protected by caps when not in use.The vast majority of large digital cameras and camcorders of recent vintage feature an internal zoom lens with a fixed front lens and standard filter threads.The robust construction of Hyperion eyepieces is capable of directly supporting heavy video and film cameras weighing up to 6.6 lb.Hyperion eyepieces are also ideal for use with so-called clamping-style universal digital camera holders, and will precisely support cameras squarely with respect to the optical axis, due to their straight forward cylindrical-shaped outer body.With or without the removable negative lens group, the Hyperion eyepiece is an incredibly sharp projection system.In combination with a short-focus objective as small as 60mm, the same afocal imaging configuration can be employed in industry for monitoring hazardous operations like plasma welding from a safe distance.

All coatings are carefully matched to the index of refraction for each of the different glass substrates used.The painstaking design and execution of baffling has all but eliminated troublesome stray light and ghost reflections. Under all conditions of illumination, the interior of a Hyperion eyepiece will appear jet black, testimony to the virtual elimination of stray light.The Hyperion has the shortest field stop position of all wide field eyepieces known.Specifically designed for binocular viewing. Ideal for use with accessory binocular viewers thanks to a tight barrel diameter (58 millimeters with the removable neoprene rubber grip ring, 56 millimeters with the grip ring removed) that permits interpupillary distance settings of as little as 56 millimeters.Each Hyperion eyepiece in the series is actually two eyepieces in one! A much longer focal length lens can be created by unscrewing the forward 1.25-inch diameter portion of barrel that houses the negative achromat lens group. Color correction remains excellent, and the field curvature that results is no greater than in a decent specimen of the 6-element Erfle design. Removing the negative lens group exposes an M48 female thread so that large-format light pollution and nebular filters can be employed.Thanks to the short 1.25 chrome sleeve of 0.94”, all Hyperion’s are principally compatible with spotting scopes, including high-end units by Leica, Swarovski, and Zeiss. The perfect eyepiece for afocal projection imaging The digital camera threads S54 and M43 x 0.75 have been incorporated into the Hyperion eyepiece for compatibility with the Baader Series 54 digital T-rings. With a Series 54 t-ring installed on the Hyperion, you can attach almost any digital and videocamera without vignetting. These threads are protected by caps when not in use.The vast majority of large digital cameras and camcorders of recent vintage feature an internal zoom lens with a fixed front lens and standard filter threads.The robust construction of Hyperion eyepieces is capable of directly supporting heavy video and film cameras weighing up to 6.6 lb.Hyperion eyepieces are also ideal for use with so-called clamping-style universal digital camera holders, and will precisely support cameras squarely with respect to the optical axis, due to their straight forward cylindrical-shaped outer body.With or without the removable negative lens group, the Hyperion eyepiece is an incredibly sharp projection system.In combination with a short-focus objective as small as 60mm, the same afocal imaging configuration can be employed in industry for monitoring hazardous operations like plasma welding from a safe distance.

Baader Planetarium 28mm Hyperion Finetuning Ring - HDFT-28

Baader 28 mm Hyperion Fine Tuning RingChange the focal length of your Hyperion eyepiece with ease using Baader's 28 mm Hyperion Fine Tuning Ring! Easily install it between the front element and the main body of the eyepiece. The Baader 28 mm Hyperion Fine Tuning Ring is made to match the Hyperion finish, and is fully sharp v-threaded and blackened internally to eliminate stray light reflections from the internal surfaces.With the addition of Baader's Fine Tuning Rings, your Hyperion eyepiece can now function as not one, but four eyepieces with the addition of the Baader 28 mm Fine Tuning Ring. Both the 14 mm Fine Tuning Ring and the 28 mm Fine Tuning Ring have an outside diameter (OD) of 2" and are threaded with an M48 (filter thread) on each end, so they can be installed in between the removable front negative element and the main body of the Hyperion eyepiece. The added spacing decreases the focal lengths (or increases magnification). Note: Removal and installation of the front negative element should be done in a clean environment to prevent dust or other contamination from depositing on the internal elements, which are very difficult to clean. Also, please be aware that the Baader 24 mm Hyperion Eyepiece is not able to make use of the Fine Tuning Rings, due to the difference in its optical design.

Baader Planetarium 90º Erecting Prism Diagonal - 2" - AMICI-2

Baader 2" 90 Degree Erect Amici Prism DiagonalThe Baader Amici Prism as long been a popular choice for generating refractor and Cassegrain-style telescope images that are oriented correctly. However, to produce an amici prism, a much more complex and higher level of quality is needed compared to the production of a standard mirror diagonal or a right angle prism diagonal. The faces of a prism must be polished smooth, flat, and located at the correct positions and angles with extreme accuracy. The sharp roof edge needs to be made so fine that it practically vanishes. Even supposed premium quality amici prisms often create images that are astigmatic or asymmetrical and show a distinct central diffraction spike. The roof edge diffraction spike of this Amici Diagonal is exceptionally faint! Baader's 2" Amici Erect Image Diagonal is made with a fine, large-sized prism.Baader Planetarium produces easily the finest amici prism star diagonal available today. The prism has been made to the proper specifications, in order to provide image quality that suffers from none of the defects found in commonly available correct image amici diagonals. The finest 7-Layer Multi-Coatings ensure the image is bright and contrasty, and the oversized prism provides the full clear aperture of 1.25"! The precision machined aluminum housing provides a stress-free mounting and precise location for the prism. This correct-image diagonal is just the thing for high-quality terrestrial viewing.Correct image diagonals have been used traditionally for terrestrial viewing and limited to low (under 100X) magnifications. The high quality of this diagonal lets you use much higher magnifications without aberrations or image breakdown.

Baader Planetarium Dielectric Mirror Telescope Diagonal with ClickLock - CLDIAG-2

Baader Planetarium 2 Inch Dielectric Diagonal With their ground-breaking introduction several years ago of the all-dielectric 2" Dielectic star diagonal, Baader Planetarium brought mirror star diagonals into the 21st century. The new 2" Clicklock Star Diagonal takes this innovation another step further. Like its predecessor, the 2" Clicklock Star Diagonal uses the proprietary Baader Dielectric mirror coatings. The Baader coating process eliminates the Achilles Heel that has plagued other all-dielectric mirror coatings - normally the multi-layer coating results in high surface stresses that cause a star diagonal's mirror to warp as much as 1/2 wave, ruining the figure and distorting the optical wavefront. Baader's proprietary coating process maintains the 1/10 wave mirror surface accuracy - After Coating! Baader's Dielectric coatings deliver an amazingly high 99% photo-visual reflectivity along with an extremely hard durable surface. The Maxbright mirror coatings will last lifetimes without losing reflectivity, and may be cleaned with normal care, without fear of scratches. The precision mirror is also oversized, and combines with the large ID nosepiece to pass the largest image cone possible in a 2" format. The new 2" Clicklock non-marring eyepiece holder delivers the same acclaimed simplicity and security as its smaller 1.25" Clicklock cousin. With an effortless twist of the rubber knurled ring (which also includes a convenient fingertip lever) , the clicklock holder clamps 2" eyepieces so securely you can lift your scope with them. The unique action utilizes 3-point clamping which positively and accurately locks 2" eyepieces without any of the wobbling and misalignment that can occur with single point clamps.

Both the 14 mm Fine Tuning Ring and the 28 mm Fine Tuning Ring have an outside diameter (OD) of 2" and are threaded with an M48 (filter thread) on each end, so they can be installed in between the removable front negative element and the main body of the Hyperion eyepiece. The added spacing decreases the focal lengths (or increases magnification). Note: Removal and installation of the front negative element should be done in a clean environment to prevent dust or other contamination from depositing on the internal elements, which are very difficult to clean. Also, please be aware that the Baader 24 mm Hyperion Eyepiece is not able to make use of the Fine Tuning Rings, due to the difference in its optical design.

Baader Planetarium Hyperion 68º Eyepiece Set - HYP-SET

Baader Planetarium Hyperion 68º Eyepiece SetThis set includes every Baader Hyperion eyepiece you need for stellar views! They even come in a fitted case for protection during traveling and when the eyepieces are not in use. The majority of telescopes come with one or two simple eyepieces that cannot take advantage of the telescope's optical performance. Weak contrast and sharpness, along with a narrow field of view ruin the enthusiasm you have for observing the night sky rather quickly. But with these Hyperion 68º eyepieces, you can unlock your telescope's full potential! Suitable for astrophotography, these eyepieces connect to cameras and camcorders to preserve your best astro-images forever. Baader 68º Hyperion Modular Eyepieces have unique photo-visual features for exceptional performance. In order to achieve genuine high-end performance from a wide-field eyepiece, amateurs previously needed to spend more on their eyepieces than on their main instrument. Not anymore. These Hyperions have undergone a complete redesign and now offer improved transmission and contrast. They're not merely a rebranded version of their revered cousins. Baader Planetarium has diligently worked to supply these multi-functional Hyperions with the finest optical coatings and superb mechanics. As a visual eyepiece, Hyperions have been found to deliver outstanding sharpness and color fidelity over their wide 68-degree flat-field, even with fast telescopes. Compared to the Pentax XL, the Hyperion proved to be the Pentax's equal in every way, but for only a third of the price! From their excellent on and off-axis sharpness to their jet black high contrast field, these Hyperions get the job done. Observing through a Hyperion is especially comfortable and relaxing because of its long 20 mm eye relief, extra-large eye lens, and optical design that eliminates that annoying "kidney-bean" effect and blackouts.

Baader Planetarium Hyperion 8mm-24mm Clickstop Zoom Telescope Eyepiece - HYP-ZOOM

The Baader Hyperion 8-24mm Clickstop Zoom continues the Hyperion tradition of delivering top-of-class performance and quality, at very reasonable prices. Zoom eyepieces have earned a lackluster reputation over the years, due to their compromises in optical design and execution. We think the Hyperion zoom will surprise many jaded zoom users with its combination of performance, quality, and novel features. Some highlights of the Hyperion Clickstop ZoomConsisting of 7 elements, the Hyperion optical design delivers outstanding sharpness and color correction over its field, even with fast telescopes. Users are reporting that the Clickstop Zoom matches the performance of their best fixed focal length eyepieces!Continuously variable focal length, with click-stops at 8, 12, 16, 20, 24mm. Remains approximately parfocal across the zoom range. Click-stops enable precise focal length matching for bino-viewer use (please note: barrel diameter of the zoom is 57mm, so it may not work in binoviewers for users with narrow interocular separations).Wide-field. The field of view is 68degrees at the 8mm setting, and 50 degrees at 24mm.Excellent viewing comfort. The eye relief of 12-15mm, large eye lens, and freedom from kidney beaning and blackouts result in a high level of comfort and ease-of-viewing, at all focal lengths.As with the fixed focal length, Hyperions Baader Planetarium has gone to great lengths to give the Hyperion Zoom the most advanced multi-coatings ever used on amateur telescope eyepieces. The Hyperion Phantom Group™ multi-coatings truly rival the best in the world - including the famous Zeiss Abbe Orthoscopic! The difference in contrast and transmission is clearly visible at the eyepiece.Now Includes both 1.25" and 2" Barrels! The 2" barrel attaches to an included adapter ring that has standard 2"x24tpi SCT threads. The 2" barrel also incorporates a reverse taper groove for better seating and retention.Superb fit and finish. Zoom motion is smooth and precise. Barrels are accurately machined, with excellent surface quality, and hard anodizing. The 1¼" Barrel is threaded for standard 1¼" filters and the 2" Barrel for standard 2" Filter.Adjustable rubber eyecup works for both normal and eyeglass users.

Baader Planetarium Hyperion T-Adapter for Eyepiece Projection Imaging - HTA43/T2

The Baader Hyperion Digital T-Adapter permits direct coupling of any T-threaded camera or accessory to the M43 thread of the Baader Hyperion Eyepieces. For the Clickstop Zoom Eyepiece, the Digital T-Adapter attaches to the M54 thread of the Zoom (located under the rubber eyeguard). These adapters give an external T-thread (M42x0.75) right at the eyelens of the Hyperions, which enables the Hyperions to be used with CCD and DSLR cameras for classic eyepiece projection photography. With this adapter, any of the Baader T-2 Extension Tubes can be used in-between the eyepiece and camera, to project and magnify the image as much as desired. The threaded direct-coupling makes this system extremely rigid and compact.Note: This Zoom model is for the new Mark III Zoom Eyepiece which has a M43 thread, the old zoom eyepieces had a M54 thread.

Baader Planetarium Hyperion Zoom 2.25x Barlow Lens - HYP-BARLOW

The Baader Hyperion Zoom Barlow quickly attaches to any Hyperion 8-24mmm Clickstop zoom eyepiece, instantly converting it into a 3.5-10.5mm Zoom. The matched optical design results in a virtually transparent 2.25X multiplication, without any optical compromises, essentially giving a 7X zoom range with outstanding optical performance throughout the 3.5-24mm range.

This spacer ring will maintain the proper optical distance of 55 mm. Allows the full 48 mm unvignetted aperture to be employed instead of 42 mm to match the Canon T-Ring.

Baader Planetarium Mark III Laser Collimator - LASER

Baader Planetarium has added a unique innovation to the laser collimator with the Mark III. The Laser Collimator incorporates a viewable etched viewing plate which can be seen through the back of the laser collimator. This permits collimation of SCTs and small diameter closed tube Newtonians, instruments that were difficult or impossible to collimate using a conventional single beam laser collimator.Each collimator is individually lathe aligned for accurate collimation. The one-piece die-cast and machined aluminum housing guarantee a stable alignment. The compact size and lightweight make the Laser Colli an indispensable tool that is handy to keep in anyone's eyepiece box (though we doubt too many will find use as a keychain).

Baader Planetarium Morpheus 76º Eyepiece Set - MORP-SET

Baader Planetarium Morpheus 76º Eyepiece SetThis Morpheus 76º Eyepiece Kit consists of six fixed focal lengths: 4.5 mm, 6.5 mm, 9 mm, 12.5 mm, 14 mm, and 17.5 mm.Containing a genuine 76º field of view, these Morpheus eyepieces allow total immersion in the cosmos without the need to roll your eyes. Giant 20 mm eye relief is ideal for comfortable viewing with glasses and contributes to a "spacewalk feeling" that you typically get only with much larger eyepieces and unattainable apparent fields of view. At the same time, the image does not appear distorted or like looking through a fishbowl in any way. Center contrast and brightness are analogous to what you would expect from the finest planetary eyepieces. Even with the fastest telescope optics, you'll experience razor-sharp stars close to the field's outermost edge. Baader Planetarium has put as much effort into the workmanship as into the optical design. Phantom Coating® Group, rare-earth glasses, sealed watertight housings, and blackened lens edges are a given. Practical design is the prime goal, that is minimum metal to keep weight at bay, optimized for bino-viewing, photo-video thread, and the all-new 1.25" and 2" "safety-kerfs" to guard against slipping (no undercut). At night you will love the quick draw eyepiece holster and the photo-luminescent engraving.

Baader Planetarium Protective Wide T-Ring System for Canon EOS - DSLRT

Baader Protective Wide T-Ring System for the Canon EOS evolves the T-Ring The 2" wide-aperture of the protective T-ring accepts 3 different attachment adapters, which are included with each T-ring: Standard T-thread (42mm), 2" thin profile nosepiece, and 48mm thread (astro filter standard). The internal filter compartment is able to accept both Baader 2" mounted filters, and 50.4mm diameter unmounted filters for the widest clear aperture possible (47.3mm aperture).The optimized design and tight manufacturing tolerances ensure the closest fit possible with the Canon EOS body. This avoids the occurrence of focal plane tilt and image shift caused by play and wobble at this connection point. The Baader Protective Wide T-Ring System includes 6 configurable parts: Protective T-ring BodyTemperature Compensation Ring (for installation of 50.4mm x3mm unmounted filters)Adapter S52/M48 (for 48mm connection thread)T-thread/M48 adapter (for standard 42mm T-thread connection)S52/2" wide aperture 2" nosepiece (includes M48 filter thread)1.5mm Allen Wrench

Baader Planetarium Reducer - 2 Inch to 1.25 Inch - T2-15

The Baader 2"/1.25" reducer permits you to convert your 2" focuser for use with 1.25" eyepieces and accessories. As with its little brother, the 2" reducer incorporates several useful features. A captive spring bronze lock ring guarantees protection of your eyepiece barrels from damage. This reducer also incorporates two large nickel-plated brass knurled clamp screws that are oriented 90 degrees apart. The inclusion of two clamp screws results in a superior 3-point attachment that completely constrains your equipment from wobble, which is particularly important for imaging applications (typical single clamp screw adapters still allow some motion). Also, for those users that are physically unable to firmly grasp and tighten lock screws, the addition of a second screw doubles the locking force (ie, particularly nice for those unable to grip tightly due to arthritis). The input side is provided with 48mm filter threads and also includes a nested internal T-2 thread which enables you to use the reducer along with the other T-2 system components. One more unique feature sets our reducer apart it includes an external T-2 thread that surrounds the eyepiece opening (covered and dressed by a knurled removable ring). This thread permits you to couple other T-2 accessories to the output side. In one application, you can attach T-2 Extension Tubes and create an extremely rigid afocal or eyepiece projection system. Once again, you are free to creatively construct your own combinations.

Baader Planetarium SCT to 2 Inch Clicklock Clamp - CLSC-2

The Baader 2” ClickLock Clamp for Schmidt-Cassegrain telescopes is a very elegant solution for holding your 2" accessories in place without slipping or sagging. Gone are the days of thumbscrews and compression rings, both of which can cause misalignment.With the Baader SCT ClickLock Clamp, all it takes is a twenty degree rotation of the rubberized knurled collar, and your accessory will be securely locked in place. Twist the adapter in the opposite direction to unlock. The collar moves very easily, and so it doesn’t take a lot of force to lock or unlock this 2” eyepiece holder.The Baader ClickLock comes with a wrench so that you can adjust the rotation of the clamp and thus position the clamp lever where you find it most convenient. Once its positioned, the Clicklock Clamp Lever will give you a visual indication of clamp’s location.This 2" ClickLock Clamp is designed for Schmidt-Cassegrain telescopes that use the standard 2” SCT thread. The accessory side accepts 2” eyepieces and accessories.The physical length of the Baader SCT 2” ClickLock Clamp is 47mm.

Baader Planetarium Semi-APO Telescope Filter - FSAPO-2

Baader's newest addition for Achromat owners. The Semi-APO works like its name implies - delivering an amazingly neutral view, while cutting most of the annoying and contrast-robbing violet fringe that plagues all achromats. The Semi-APO filter combines a stronger Fringe Killer coating formula with the Moon&andSkyglow Neodymium substrate. The result is similar performance to the Fringe Killer + Moon&andSkyglow combination, but with a slightly stronger violet cut - and at an even greater $$ value.The Semi-APO filter benefits from all the host of world-class Baader filter attributes. The Semi-APO filter is truly the world's most advanced 'minus-violet' type filter in every regard. Its high efficiency and neutral coloration make it practically disappear in use - while making most of the violet fringe disappear! The effects on sharpness, contrast, and aesthetics are remarkable, even with small refractors. The RGB enhancement of the Neodymium substrate actually boosts color contrasts, particularly for Jupiter and Mars. As a side benefit, the Semi-APO filter has also proven to be the best Mars filter we've used - with ALL Telescopes, including large Dobsonians, SCTs, and Apochromats. The unique properties that result from the combination of the Fringe Killer's blue wavelength attenuation (attenuation - not total elimination), plus the selective Neodymium RGB passbands, result in a significant contrast enhancement of Martian features. The image retains its natural coloration and brightness, and the optically polished surfaces maintain every bit of the image sharpness, unlike other manufacturers' filters. The high quality of Baader Planetarium filters permits their use well ahead of the focal plane with no image degradation (ie, for cameras or binoviewers). The inclusion of Baader's renowned UV/IR Cut coatings on the Semi-APO eliminate UV and IR wavelengths to make it ideal for high-resolution imaging with Webcams, DSLR, and CCD cameras. The high transmission and fringe reduction work great for both planetary and deep sky imaging.

Baader Planetarium Sky Surfer III 30 mm Red Dot Finder - SSIII

Baader 30 mm Sky Surfer III Red Dot FinderFinding objects in dim star fields or light polluted skies is now easier than ever with Baader's 30 mm Sky Surfer III Red Dot Finder. The extra-large 30 mm optical aperture and improved optical quality delivers a much larger undistorted view and razor-sharp red dot. Unlike many red-dot finders, the Sky Surfer III incorporates optimized anti-reflective lens coatings which deliver proper locator dot brightness with virtually no image dimming. One other new feature you will really come to appreciate is the extra-long lens housing, which acts as a shield to effectively prevent dew problems.Mounting and adjustment of the Sky Surfer is simple. Elevation and Azimuth adjustment is accomplished by turning the two knurled adjustment knobs. The red locator dot intensity is adjusted by a knurled adjusting knob. Attachment to your telescope is also straightforward, with all necessary parts included. Simply attach a base to your telescope, slip on the finder, and tighten the two dovetail clamp screws.Three bases are included: The short base works best for large tubes. It includes two mounting slots (for screw mounting) and may also be attached with double sided foam tape (which is supplied). The taller base fits smaller diameter tubes (as well as large tubes using the included spacer plate) and the slotted holes accommodate the factory hole pattern of popular SCTs. The third base fits the Vixen finder dovetail standard, as used on many imported refractors. Each Sky Surfer includes a replaceable 3 Volt lithium battery for extra long life.

Baader Planetarium Visual AstroSolar Safety Film - 7.9" x 11.4" Sheet - ASOLV-S

Baader AstroSolar Visual Safety Film A4 Sheet - 7.9 x 11.4"Baader Planetarium's Astro Solar Film makes viewing the Sun safe and fun. The safety film projects white light views of the Sun that are unparalleled to any other solar filters or material out there. Portraying fine solar detail, Baader's Astro Solar Film display penumbral detail, solar granulation, and lighter colored faculae. The film is set against a dark background, free of haze and scatter. Great performance at a great price!Baader AstroSolar Visual Safety Film Size 20 x 29 cm presents the Sun in its real color which is neutral white. The competition provides films and glass filters that produce a blurry bluish or reddish/orange/yellow solar image which in turn cuts part of the spectrum. With an orange Sun, it is very hard to see faculae regions which are visible predominantly in the blue wing of the spectrum. Because of AstroSolar's neutral color balance, this allows the use of various color (or interference) filters that allow observers to focus on particular spectral passbands for investigations or different layers within the solar "atmosphere".In solar observation, eye safety is critical! Baader's AstroSolar is essentially free from pinholes because of the coating on both sides so that the chances of two pinholes overlapping each other is extremely small. While pinholes do appear the ratio is 1 out of 10,000 only, in optical density 2.5! All coatings are inspected continually for consistency and for eye safety. With Baader AstroSolar Visual Safety Film Size 20 x 29 cm, enthusiasts will enjoy the Sun's hidden grandeur at a fraction of the cost but will experience high-quality performance in every use.

Known for viewing planetary detail and splitting close double-stars.A refractor telescope uses a lens as the primary. The lens at the front of the telescope bends the light passing through it until it comes to a single point called the “focal plane”. The long, thin tubes of refractor telescopes look much the same as those Galileo used centuries ago. High-quality optical glass and multi-coatings provide today’s skywatchers views Galileo never dreamed of.The refractor type of telescope is very popular with individuals who want mechanical simplicity, rugged reliability, and ease of use. Because the focal length is limited by the length of the tube, refractor telescopes become quite bulky and expensive beyond a four-inch aperture. This limits the light gathering properties of refractor telescopes, but it is an excellent choice for beginners and those who prefer simple operation and versatility. Refractor telescopes are also a popular choice because of their unobstructed view, high contrast and good definition.Refractor Advantages Easy to set-up and useSimple and reliable design requires little or no maintenanceExcellent for lunar, planetary and binary star observing especially in larger aperturesGood for terrestrial viewingHigh contrast images with no secondary mirror or diagonal obstructionColor correction is good in achromatic designs and excellent in apochromatic and fluorite designsSealed optical tube reduces image-degrading air currents and protects opticsObjective lens is permanently mounted and alignedRefractor Disadvantages More expensive per inch of aperture than Newtonians or CatadioptricsHeavier, longer and bulkier than equivalent aperture Newtonians and CatadioptricsThe cost and size factors limit the practical maximum size primary to smaller aperturesSome color aberration in achromatic designs (doublet)

Ready For Astrophotography?The rewards of capturing images from space are endless - so are the accessories and techniques for doing it! The Celestron CPC telescopes are an amazing tool for astrophotography. While we are not going into long detail of astrophotography technique, we will cover here what accessories are used for astrophotography with the CPC series telescopes. There are different methods of mating your particular camera to the CPC, or other choices of astrophotography tools you should know about: DSLR Imaging - One of the fastest growing and most popular methods of astrophotography is using DSLR Cameras. The most popular digital SLR cameras are from Nikon and Canon. To connect a DSLR camera to your CPC telescope, you will need 2 pieces - A T-Adapter and a T-Ring. To connect your DSLR camera you will need to remove the lens from the camera, and replace it with a T-Ring. With the appropriate T-Ring attached to your DSLR camera you will then be able to connect your camera body directly to the T-Adapter connected to your CPC telescope. Preventing Dew with the 11 Inch CPC TelescopeDew forming on the lens of your telescope can quickly end an evening of observing. Once dew has formed, its very difficult to get rid of it. The answer is to prevent it from happening at all. Dew prevention can mean taking full advantage of those rare clear sky evenings or packing it in early.There are two methods of preventing dew from forming. Dew Shields and Dew Heaters. About Celestron Schmidt-Cassegrain TelescopesCelestron’s excellent Schmidt-Cassegrain telescopes are compact and portable and represent the best all-purpose design for a wide variety of uses from terrestrial and deep sky viewing to astrophotography.Catadioptrics use a combination of mirrors and lenses to "fold" (reflect) the light path and form an image. In a Schmidt-Cassegrain, the light enters through a thin aspheric Schmidt correcting lens. It then strikes the spherical primary mirror. It is reflected back up the tube and intercepted by a small secondary mirror which reflects the light out an opening in the rear of the instrument where the image is formed at the eyepiece.Catadioptrics are the most popular and most modern type of telescope optical design and are marketed throughout the world in 3.5" and larger apertures. Catadioptric telescopes combine the practical advantages of lenses and mirrors while eliminating their disadvantages. They offer the clarity and contrast of refractors with the low aberration of reflectors. Catadioptrics have an average focal ratio of f/10, which is wide enough for all types of photography. They are also easier to maintain because all optical elements are solidly mounted and rigidly collimated. Catadioptric telescopes provide the best possible combination of light gathering power, long focal length, portability and affordability.

About Celestron Refractor TelescopesCelestron’s high-quality refractor telescopes allow beginners to improve upon Galileo’s vision with a simple, reliable design that is easy to use, requires minimal maintenance, and is versatile enough for land or sky viewing. Known for viewing planetary detail and splitting close double-stars.A refractor telescope uses a lens as the primary. The lens at the front of the telescope bends the light passing through it until it comes to a single point called the “focal plane”. The long, thin tubes of refractor telescopes look much the same as those Galileo used centuries ago. High-quality optical glass and multi-coatings provide today’s skywatchers views Galileo never dreamed of.The refractor type of telescope is very popular with individuals who want mechanical simplicity, rugged reliability, and ease of use. Because the focal length is limited by the length of the tube, refractor telescopes become quite bulky and expensive beyond a four-inch aperture. This limits the light gathering properties of refractor telescopes, but it is an excellent choice for beginners and those who prefer simple operation and versatility. Refractor telescopes are also a popular choice because of their unobstructed view, high contrast and good definition.

With the telescope you already own and this diagonal, you can enjoy bright views with sharp detail. No need to purchase an entirely new optical system to get a better view.This star diagonal reflects the telescope’s light path 90° to provide a more comfortable viewing angle. In addition, the glass has 58 layers of dielectric coatings, which provide a more than 99% reflective surface, delivering the maximum amount of light to the eyepiece. Plus, the included 1.25" stepdown adapter enables compatibility with larger 2" eyepieces for an expanded field of view, along with standard 1.25" eyepieces.2" eyepieces are kept secure and centered in the diagonal by the twist-lock holder for optimal opto-mechanical alignment between telescope and eyepiece. Twist-lock is unable to scratch or engrave your eyepiece barrel unlike conventional thumb screws. A built-in 2" barrel stop protects the mirror from being damaged by 2" accessories with long barrels.Except for the twist lock ring which is orange anodized to enhance visibility, this diagonal’s construction consists of black anodized aluminum. Both the SCT adapter and 2" barrel interior are glare threaded and painted flat black to minimize glare. Taken together, the Celestron 2” Dielectric Star Diagonal’s features and high-end finishes make it one of the best 2” star diagonals ever offered by Celestron in terms of quality.Two interchangeable barrels are also included with this diagonal to enable the flexibility necessary for connection to a wide range of telescopes without the need for supplemental adapters. A standard 2" barrel is included for telescopes, such as refractors, that accept 2" barrels in their focuser, while an SCT threaded barrel is included for Schmidt-Cassegrain telescopes. Each barrel threads onto the diagonal housing for secure attachment to the diagonal. Standard Star Diagonals vs Dielectric Star Diagonals Reflectivity and optical quality are the key specifications for a star diagonal. This dielectric diagonal delivers top performance in both categories, with an over 99% reflective mirror and diffraction-limited optical quality to ensure that virtually all the light collected by the telescope reaches your eyepiece without the diagonal having an impact on optical performance. Using a lower quality star diagonal can both dim the view and degrade optical quality. You can instantly improve the views you experience through your telescope by simply swapping out its diagonal for a premium Celestron Dielectric Star Diagonal.

About Celestron Schmidt-Cassegrain TelescopesCelestron’s excellent Schmidt-Cassegrain telescopes are compact and portable and represent the best all-purpose design for a wide variety of uses from terrestrial and deep sky viewing to astrophotography.Catadioptrics use a combination of mirrors and lenses to "fold" (reflect) the light path and form an image. In a Schmidt-Cassegrain, the light enters through a thin aspheric Schmidt correcting lens. It then strikes the spherical primary mirror. It is reflected back up the tube and intercepted by a small secondary mirror which reflects the light out an opening in the rear of the instrument where the image is formed at the eyepiece.Catadioptrics are the most popular and most modern type of telescope optical design and are marketed throughout the world in 3.5" and larger apertures. Catadioptric telescopes combine the practical advantages of lenses and mirrors while eliminating their disadvantages. They offer the clarity and contrast of refractors with the low aberration of reflectors. Catadioptrics have an average focal ratio of f/10, which is wide enough for all types of photography. They are also easier to maintain because all optical elements are solidly mounted and rigidly collimated. Catadioptric telescopes provide the best possible combination of light gathering power, long focal length, portability and affordability.Schmidt-Cassegrain AdvantagesVery versatile, best all-purpose telescope designCombines the optical advantages of both lenses and mirrors while eliminating their disadvantagesExcellent optics and razor sharp images over a wide fieldExcellent for deep sky observing and astrophotography as well as terrestrial viewingVery good for lunar, planetary and binary star observingFocal ratio generally around f/10, it also has the best near focus capability of any type of telescopeClosed tube design reduces image-degrading air currentsExtremely compact and portableEasy to use, durable and virtually maintenance freeLarge apertures at reasonable cost and less expensive than equivalent aperture refractorsMore accessories available than with other types of telescopesSchmidt-Cassegrain Disadvantages More expensive than Newtonians of equal apertureSlight light loss due to secondary mirror obstruction compared to refractors The Maksutov-Cassegrain is similar to the Schmidt-Cassegrain with essentially the same advantages and disadvantages. It uses a thick meniscus correcting lens with a strong curvature and a secondary mirror that is usually an aluminized spot on the corrector.

Celestron 8" Rowe-Ackermann Schmidt Astrograph OTA - 91073

Celestron 8" RASA Astrograph Optical Tube With this new portable Celestron astrograph, the 8" RASA (Rowe-Ackermann Schmidt Astrograph), you'll be able to capture breathtaking wide field views of deep sky objects in a matter of seconds. The 8" RASA's awesomely fast f/2.0 optical system works perfectly in conjuction with modern color astronomical CMOS, smaller CCD, and mirrorless cameras. This combination of a fast focal ratio and patented optical design generates sharp images with superb detail, and, in many instances, allows you to completely skip the autoguider. Plus, as it weighs only 17 pounds, transporting your 8" RASA to distant dark sky locations is easy. RASA Performance Made For EveryoneThe Celestron 8" RASA is an imaging telescope that delivers a flat field without optical aberrations for razor sharp stars across a wide field of view. It is capable of capturing stunning deep sky astronomical images without the challenges typically presented by longer focal length instruments at a fraction of the cost of those systems.This 8" model is the most recent addition to the RASA lineup. It offers greater portability and is much more affordable when compared to the popular 11" RASA which was highly acclaimed when it was introduced in 2014. With the addition of the economical 8" RASA, more astrophotographers will be able to take advantage of the Rowe-Ackermann design. This 8" and 11" RASAs share many of the same attentively designed features such as a built-in air-cooling system, internal filter mount, and durable CGE dovetail mounting bar.Designed purely for imaging, the Celestron 8" RASA will not work as a visual instrument. Since the prime focus focal plane is located at the front of the optical system, it cannot accommodate a traditional eyepiece. Shorter Exposure Times and Virtual "Real-Time" ObservingDue to its extremely fast f/2.0 optical system, imagers can use minimal exposure times with the 8" RASA to capture enhanced detail in dim targets. When employed in conjunction with sensitive cameras and the appropriate "live stacking" software, the 8" RASA is capable of delivering a virtual real-time observing experience. Instantly view images on a computer with more brightness and detail than can be viewed with the naked eye using much larger telescopes. Ultra-Stable Focus SystemWith the launch of the 8” RASA, Celestron is unveiling a new focuser design that mitigates lateral movement of the primary mirror when focusing, slewing, or tracking with the astrograph. Focusing is easier, more accurate, and more stable than ever. The key to the Ultra-Stable Focus System is two sets of precision bearings that are precisely aligned and tested during assembly to ensure optimal results. Built for Today's Latest CamerasContrary to larger Rowe-Ackermann Schmidt Astrographs that are compatible with DSLR and large CCD cameras, the 8" version was designed with regards to color astronomical CMOS cameras, smaller CCD cameras, and mirrorless cameras. This telescope is not suitable for use with standard DSLR cameras. Optimized for up to 22 mm diagonal sensors, the 8" RASA also offers sufficient performance with sensors up to 32 mm diagonal. Many mirrorless cameras use APS-C sized sensors that would be an excellent option. 42 mm full frame sensors are also compatible, but performance will suffer at the edges of the sensor while field illumination is decreased. Furthermore, Celestron does not recommend pairing the 8" RASA with any 4" diameter or larger camera body.

Celestron 8" Rowe-Ackermann Schmidt Astrograph with CGEM II Equatorial Mount - 12020

Celestron CGEM II 800 RASA With the combination of this 8" Rowe-Ackermann Schmidt Astrograph (RASA) and CGEM II German Equatorial Mount kit, plus an optional camera, you'll have everything necessary to capture breathtaking images of wide-field deep sky wonders. RASA Performance Made For EveryoneCapture incredible wide-field images of deep sky objects in only seconds with this portable Celestron 8" Rowe-Ackermann Schmidt Astrograph (RASA). With its exceptionally fast f/2.0 optical system, the 8" RASA provides an ideal complement to modern color astronomical CMOS cameras, smaller CCD cameras, and mirrorless cameras. This fast focal ratio and patented optical design generates sharp images with terrific detail that will allow you to skip the autoguider altogether in many cases. Weighing in at a modest 17 lbs. allows the 8" RASA to be easily transported to most remote dark sky sites.Delivering a flat field free of optical aberrations, this Celestron 8" RASA imaging telescope provides razor sharp stars over the entire field of view. For a much more affordable cost compared to longer focal length telescopes, the 8" RASA is capable of capturing spectacular images of deep sky objects without the issues typically encounted with these aforementioned systems.The latest addition to the RASA family, this 8" version offers greater portability at a much reduced cost compared to the highly touted 11" RASA, which was launced in 2014 to much acclaim. With the addition of the 8" RASA to the lineup, a wider range of astrophotographers will now be able to enjoy the RASA design's benefits. Many of the same thoughtfully designed features present in the 11" RASA are also present in the 8" RASA such as the integrated air-cooling system, internal filter mount, and sturdy CGE dovetail mounting bar.Made specifically for imaging applications, the 8" RASA is not suitable for visual use. Traditional eyepieces cannot be accommodated as the prime focus focal plane is located at the front of the optical system. Shorter Exposure Times and Virtual "Real-Time" ObservingSince the 8" RASA has an f/2.0 optical system, imagers are able to use shorter exposure times to capture detail in faint objects. When combined with sensitive cameras and proper "live stacking" software, this astrograph telescope can provide an almost real-time observing experience. View images on a computer instantly that are brighter and more detailed than can be seen in much bigger telescopes with the naked eye. Ultra-Stable Focus SystemTo coincide with the launch of the 8" RASA, Celestron is introducing a new focuser design that alleviates lateral movement of the primary mirror while the telescope is focusing, slewing, or tracking. This makes focusing easier, as well as more stable and accurate than ever before. At the core of this Ultra-Stable Focus System is two sets of precision bearings that have been precisely aligned and tested during construction for results that are guaranteed to be optimal. Built for Today's Latest CamerasContrary to larger Rowe-Ackermann Schmidt Astrographs that are compatible with DSLR and large CCD cameras, the 8" version was designed with regards to color astronomical CMOS cameras, smaller CCD cameras, and mirrorless cameras. This telescope is not suitable for use with standard DSLR cameras. Optimized for up to 22mm diagonal sensors, the 8" RASA also offers sufficient performance with sensors up to 32mm diagonal. Many mirrorless cameras use APS-C sized sensors that would be an excellent option. 42mm full frame sensors are also compatible, but performance will suffer at the edges of the sensor while field illumination is decreased. Furthermore, Celestron does not recommend pairing the 8" RASA with any 4" diameter or larger camera body. Unique Optical DesignCelestron's patented RASA optical design contains a Schmidt corrector, primary mirror, lens group, and optical window. The lens group utilizes four rare-earth elements. The 8" RASA's optics are designed to perform over a wider spectral range compared to many other telescope designs. While most telescopes only function well over the visual region of the spectrum (400-700 nm), the 8" RASA functions well over an extended 390-800 nm spectral range. Because of this, more light emitted from your target astronomical object is allowed to be sharply focused in the image.With many imaging systems, optical performance will not be affected by the addition of an extra piece of flat glass such as a filter. This is not the case, however, with telescopes that features ultra fast optics like the RASA. To address this, Celestron's engineers have added a detachable optical window to the RASA design to enable maximum optical performance preservation even if a filter is added or if a camera already contains its own optical window. A Light Pollution Imaging Filter expressly designed for the 8" RASA is available as an optional accessory that takes the place of the optical window.Celestron StarBright XLT coatings cover all refractive optical surfaces, while enhanced aluminum coatings cover the primary mirror. This keeps light transmission high throughout the whole optical system. With the 8" RASA, you'll get better optical performance and field illumination than with "Hyperstar SCT" systems.Celestron CGEM II Computerized GoTo Equatorial Mount The Celestron CGEM mount has been a very popular equatorial platform for several years, but never a company to “gather moss”, it was decided that the Celestron CGEM should have a make-over on the outside and the inside.At first glance, one can see that the Celestron CGEM II equatorial mount is more ergonomic than its predecessor, with longer lock levers to make it easier to make adjustments to your mount. Also, the new heavy duty dual-style saddle plate is designed to accept either CG-5 (Vixen) or CGEM (Losmandy) mounting dovetails so that virtually any optical tube assembly can be mounted in minutes without the need for an adapter.Celestron CGEM II series mounts offer a generous weight capacity of 40 lbs. Optical tubes as heavy as an 11" EdgeHD can be attached to this portable yet sturdy mount, while still being able to easily break it down into manageable pieces for travel to star parties or dark sky sites near you. The CGEM II mount weighs 40 lbs. without counterweights and the tripod, which has also been updated, and weighs just 20 lbs.Speaking of the tripod, this model has 2” stainless steel legs for rigidity and support, with graduated markings on each leg to make leveling fast and easy. The spreader bar pushes against the legs to make them incredibly sturdy, while the interior of the spreader offers receptacles for a few extra eyepieces so they are in easy reach when observing.The electronics of the Celestron CGEM II, whether designed for the previous CGEM or new to the CGEM II model, will allow you to set up, use, and maintain your mount with these innovative features:A built-in All-Star Polar Alignment program lets you accurately polar align on any star in the sky without having a view of the celestial pole. No polar finderscope necessary!Past the meridian tracking for seamless imaging across the best part of the sky.With PPEC, or Permanent Periodic Error Correction, you can train out the periodic error on your worm gears once, and the system will remember the PEC recordings.The CGEM II is capable of slewing at 5º per second, getting you where you want to go fast!There is a USB 2.0 port on the bottom of the NexStar GoTo controller to allow you to not only update the firmware of both the controller and the mount, but to connect directly to a PC with your own ASCOM-supported software.With the touch of a button you can visit over 40,000 stars, galaxies, nebulae, planets, clusters, and more.
