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 sky watchers 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)

Celestron Oxygen III Narrowband Filter - 1.25 Inch - 93623

Celestron's 1.25-inch, Oxygen III narrowband filter is a must for viewing nebulae.Oxygen III filters transmit wavelengths from the two doubly ionized oxygen lines but block virtually all others. That gives increased detail and improved contrast when viewing diffuse and planetary nebulae. You'll get stunning views of the Veil, Ring, Dumbbell, Crescent and Orion nebulae, among other objects.Each filter has an ultra-hard, vacuum-deposited coating carefully designed to block all of the visual spectrum ranging from 400 to 700 nm. This eliminates the unnatural, colored halos surrounding bright stars common with OIII filters of less-sophisticated coating technology. The 1-1/4" OIII narrowband filter isolates just the two doubly-ionized oxygen lines (496 and 501nm lines) emitted by planetary and emission nebulae, while blocking the rest of the overall spectrum of light. The result is extreme contrast between the black sky background and the faint photons of OIII light needed for detailed views of the Veil, Ring, Dumbbell, Crescent and Orion nebulae, among other objects. Each filter has an ultra hard, vacuum-deposited coating carefully designed to block all of the visual spectrum ranging from 400 to 700 nm This eliminates the un-natural colored halos surrounding bright stars common with O III filters of less sophisticated coating technology.

Celestron PowerTank Lithium Battery Pack - 18771

Say goodbye to bulky batteries and explore new dark sky sites with your telescope and this ultra-portable lithium battery pack by Celestron. Measuring just 7.5" tall and 3" in diameter, PowerTank Lithium boasts and 84.4 Wh capacity--enough power for up to 10 hours of observation!Lithium ion technology comes to your telescopeYou already trust lithium batteries to power your mobile device. But Celestron's new LiFeO4 lithium phosphate batteries significantly outperform even traditional lithium ion batteries found in handheld electronics.If you already own a sealed lead acid telescope battery, you know that they have an uncharged shelf life of just 6-9 months. Twice a year, you have to fully drain and recharge the battery to keep it in good working order. Traditional lithium ion batteries do a little better, with a 3 year average shelf life. But PowerTank Lithium boasts a shelf life of 10 years. PowerTank Lithium also blows the competition away when it comes to lifetime charge cycles: 2000 versus 500 for lithium ion and 300 for sealed lead acid telescope batteries.The lithium phosphate battery inside PowerTank Lithium is the battery of choice for many of today's electric vehicles thanks to its rugged construction and ability to withstand higher temperatures than lithium ion technology. Plus, since it contains phosphates instead of hazardous materials like cobalt and lead, it's a more environmentally-friendly option. Perhaps most important, lithium phosphate batteries do not pose a fire hazard if a cell is accidentally punctured.PowerTank Lithium redefines the telescope power supplyWith its impressive capacity, you'll have to worry about the sun coming up before your battery runs out. With power to spare, you can even tap into your PowerTank Lithium to top off electronic devices like smartphones, tablets, and portable GPS receivers via two built-in USB ports.

Celestron PowerTank Lithium LT - 18763

Celestron PowerTank Lithium LT Power your telescope on the go with the PowerTank Lithium LT, Celestron's most compact and lightweight lithium-ion power pack. It won't take long for this handy device to become a vital component of your telescope accessory kit, camping gear, emergency kit, and more. Stable Power Designed for Telescopes Made with Lithium Nickel Manganese Cobalt Oxide [LiNiMnCoO2] or NMC technology, the PowerTank Lithium LT provides a constant charge for extended periods while requiring less maintenance compared to a conventional sealed lead-acid battery.Expressly designed for astronomers by astronomers with regards to the unique requirements of computerized telescopes, the PowerTank Lithium LT is not like other lithium-ion power packs in the same price range.Telescope electronics are extremely sensitive to voltage. Powering a telescope using less than ideal voltage puts unnecessary burden on the motors with heavier payloads and can even cause glitches in the electronics. With the PowerTank Lithium LT, a built-in voltage regulator makes sure that at least 11.8 volts is delivered for the majority of the battery's life, until the battery is depleted and shuts off.You may see competitors claim that their batteries hold enough watt-hours of electricity to power your telescope for hours. The technology in these batteries was originally developed to power much lower-voltage electronics, such as home CPAP machines. Although the voltage actually being delivered starts off at 12V, it diminishes rapidly, impacting your telescope’s performance and becoming functionally useless within about 2-3 hours.Celestron’s telescope engineers worked hand-in-hand with battery suppliers on the PowerTank Lithium LT to make sure that it does not experience this dropoff in performance. The built-in voltage regulator ensures a stable 12V output, regardless of the amount of charge left in the battery. This keeps your telescope’s electronics safe and performing their best, so you can focus on astronomy.The PowerTank Lithium LT uses batteries with NMC chemistry while most typical batteries found on the market today use Lithium Cobalt Oxide. NMC batteries offer several more advantages including having a longer shelf life, three times the number of charge cycles compared to LiCoO2 chemistry, overcharge and over-discharge protection, and the ability to withstand temperatures as high as 100ºF (60ºC) greater to minimize the chance of them experiencing thermal runaway.Compared to a lead-acid battery, the PowerTank Lithium LT is smaller, lighter, more efficient, and better for the environment. It offers better performance, a longer lifespan, and safer operation than other low-cost lithium-ion battery chemistries. Features include automatic shut-off, reverse polarity protection, charging/discharging protection, overcurrent protection, and short circuit protection. Use in the Field An exceptionally portable form factor allows the power pack to be taken with you just about anywhere from remote dark sky locations to distant campgrounds. The unit secures to a tripod leg using included 2" strap so that it isn't in the way while it's busy powering your telescope. Other than the power cable need to charge your telescope, no additional cables are required.If you need to power your telescope and charge electronic devices simultaneously, the PowerTank Lithium LT features two output ports: one 12V DC port for the telescope and one fast-charging 2.1A USB charging port for smartphones and tablets. This USB port can also support any accessories that require 5V USB power. Travel with PowerTank Take the PowerTank Lithium LT with you on your next vacation. At 73.3 watt-hours, it meets current FAA regulations (160 Wh) for transportation in your carry-on baggage. Please check in advance with your airline to verify they do not have stricter policies. Do not place PowerTank Lithium LT in your checked baggage.

The PowerTank Pro is much more compact than similar rechargeable power supplies. The PowerTank Pro surpasses lithium-ion and sealed lead acid batteries because it uses Lithium Iron Phosphate chemistry, which offers these fantastic benefits:Up to 2000 charge cycles - way more than both lithium-ion or sealed lead acid designsA un-recharged shelf life of up to 10 years - a huge improvementBattery performance doesn't degrade as quickly as other chemistriesLithium Iron Phosphate (LiFePO4) is safer than other designs - it won't be a fire danger if punctured, and it can withstand higher temperatures than other batteriesThe PowerTank Lithium Pro does not use toxic heavy metals like cobalt or lead. Instead, LiFePO4 uses phosphate, which is much more environmentally friendly.Because of the advanced chemistry and design, the Power Tank Lithium is smaller, lighter, safer, and easier to maintain! Uses for the Celestron PowerTank Lithium ProStrap this 4.5-pound self-contained power supply to your telescope's tripod leg, plug it in, and power your observing sessions! Since it is cylinder-shaped and is just 8.75" tall and 6" wide, the Powertank Lithium Pro won't get in your way, and because the controls are on the top of the PowerTank Pro, it is easy to see the status and turn the battery off and on.Charge your smartphone and/or tablet, not to mention your camera or any other USB-powered device! The PowerTank Lithium has two USB Charging Ports, both at 5VDC. One puts out 2100mA and the other supports rapid charging. This large capacity power supply can be your emergency back-up at home or on the road. When the PowerTank Lithium needs recharging, the included Charger plugs into the wall and takes about 6 hours.The Celestron PowerTank Lithium Pro has an LED light panel on one side that can put extra illumination where you need it. Remember, because this power supply is just 8.75" x 6" and weighs just 4.5 pounds, it can be picked up when necessary to shine a light where you need it. You have a choice of white or red light with two different brightness settings for each. Okay, so this will never take the place of a hand-held flashlight, but we like the fact that you can use the Powertank Lithium Pro in a pinch.

Celestron Regal Premium Tripod - 82052

The Celestron Regal Premium Tripod is the perfectly portable compliment to a spotting scope, small telescope, camera, or binoculars mounted on a tripod adapter. The Regal Premium Tripod comes with a two-way fluid pan head with an upgraded quick release plate, legs that are fast and easy to adjust in both length and angle, and a handy retractable hook that will allow you to add stability to your equipment on windy days.Fully adjustable tripod legsThe Celestron Regal Premium Tripod comes with aluminum legs that are fully adjustable. They each have four telescoping sections that extend easily and lock into place with ergonomic flip levers. Drop each section down as needed, flip the lock lever closed, and move on to the next. The length of each tripod leg section can be adjusted anywhere along its length. The maximum height for the Regal Tripod is 59 inches without making use of the column extension, and 69 inches if you extend the column to its full height. All three tripod legs are also adjustable when it comes to their angle position. This is a particularly nice feature if you find yourself setting up on ground that isn't perfectly flat. A release lever is located at the top of each tripod leg, allowing you to choose from three different leg locations. A bubble level on the top of the tripod will assist you in leveling your equipment as you make adjustments to the legs.Leg padding is easy on the shoulderMost people carry their tripod from place to place by slinging it over their shoulder. This can be uncomfortable without padding. Thanks to Celestron, two of the three tripod legs have cushioning wrapped around the uppermost section. This welcome feature also gives you a place to grab the tripod when working in cold conditions.Extendable column with retractable hookThe Celestron Regal Premium Tripod comes with an extendable center column. This not only allows users to raise the height of the tripod past what the legs alone would allow, it provides a way to stabilize the tripod in windy conditions. How? Celestron added a retractable hook to the end of the column. Whenever you want extra stability, simply pull the hook into position and then hang something heavy on it. Anything will work, as long as it has some weight to it. Nature photographers often carry a bag with a handle or a string closure that can be used for this purpose, and then they put rocks, sand, or whatever else is lying nearby into the bag. When you don't need the hook, just push it back into the center column. Fluid pan head for smooth trackingThe two way fluid pan head, included with the Regal Premium Tripod, makes it easy to smoothly follow moving objects. Simply grab the handle to pan the head up, down, right, or left, and then lock it in position with the head's oversized knob. A standard 1/ 4-20 thread quick release plate makes it easy to attach a spotting scope, binocular, camera, or small telescope to the Regal tripod. The quick release plate can also perform as a balance rail, allowing your equipment to be balanced as it is being attached to the tripod. The plate also has a safety mechanism that prevents it from sliding completely out of the pan head without first pushing the release button. Spiked or rubber feet - your choiceThe Regal Premium Tripod sports innovative adjustable feet. For asphalt, cement, interior flooring and other hard surfaces, use the rubber feet. However, if you are on sand, dirt, or any terrain that could do with a little more grabbing power, simply turn each rubber foot to reveal a spike. Spiked feet will help your tripod to dig into the surface, thereby increasing stability.

Celestron RSR Binocular Tripod Adapter - 82030

This isn’t just any binocular tripod adapter! Sure, the Celestron RSR Binocular Tripod Adapter mounts to most any pair of binoculars and connects them to a camera tripod for hand’s free, steady viewing, but it also comes with a unique RSR Reflex Sight Rail that accepts a “red dot finder”! Just think of how cool it will be to align your red dot finder to the view through your binoculars. Not only will it look high-tech, you will be able to locate objects more quickly and easily.The RSR Binocular Tripod Adapter itself is simple yet effective design. The top part of the adapter threads into the tripod adapter port of most binoculars with a 1/4-20 bolt, and then the foot of the adapter connects to a standard photographic tripod via the tripod's mounting screw. You are welcome to use the binocular tripod adapter section just like this if you want. The Reflex Sight Rail is a separate piece, and can be attached to the tripod adapter in just a few seconds.Once your binoculars have been securely connected to your tripod, you can enjoy hands-free observing for long periods of time without arm fatigue or image shake.As we’ve mentioned earlier, the RSR portion of the binocular tripod adapter attaches in seconds. It has a narrow rail at the top to accept any standard reflex sight, or red dot finder. If you don’t already have one, Celestron makes the StarPointer and StarPointer Pro finderscopes, and either one attaches easily to the rail.A Binocular Tripod Adapter is essential for larger, heavy binoculars as well as high magnification models of over 12X. You will be amazed at how much easier binocular observing will become once you've taken the load off! Small objects that are hard to resolve when hand-holding will appear steady when your binoculars are on a tripod, this is especially true for astronomical objects like Saturn or Jupiter. Want to see the rings of Saturn or the moons of Jupiter? Put your binoculars on a tripod!Please Note: While most binoculars on the market today have a tripod adapter port, not all of them do. Before you buy a Binocular Tripod Adapter, check your binoculars to make sure they will be compatible. Most adapter ports are disguised by a "beauty cover" that is about the size of a nickel or dime, and it is normally located on the bridge of the binoculars between the two objective lenses. Unscrew the cover cap to reveal a 1/4-20 threaded hole.

Light enters the tube traveling to the mirror at the back end. Light is then "bent" forward in the tube to a single point, its focal plane. A flat mirror called a "diagonal" intercepts the light and points it out the side of the tube at right angles to the tube through the eyepiece. The eyepiece is placed there for easy viewing. Newtonian Reflector telescopes replace heavy lenses with mirrors to collect and focus the light, providing much more light gathering power for the money.You can have focal lengths up to 1000 mm and still enjoy a telescope that is relatively compact and portable. Newtonian Reflector telescopes do require more care and maintenance because the primary mirror is exposed to air and dust. However, this small drawback does not hamper this type of telescope's popularity with those who want an economical telescope that can still resolve faint, distant objects. Newtonian reflectors produce a "right-side-up image" but the image will appear rotated based on the location of the eyepiece holder in relation to the ground. Newtonian reflectors are best for astronomical use where right-side-up does not matter. Newtonian Advantages Lowest cost per inch of aperture compared to Refractors and Catadioptrics since mirrors can be produced at less cost than lenses in medium to large aperturesReasonably compact and portable up to focal lengths of 1000 mmExcellent for faint deep sky objects such as remote galaxies, nebulae and star clusters due to the generally fast focal ratios (f/4 to f/8)Adequate for lunar and planetary workGood for deep sky astrophotography (but not as convenient and more difficult to use than Catadioptrics)Free of color aberration due to the use of a primary mirrorNewtonian Disadvantages Generally not suited for terrestrial applicationsSlight light loss due to secondary (diagonal) obstruction when compared with Refractors

Celestron Star Pointer Finderscope - 51630

A red dot finderscope like the Celestron Star Pointer is the fastest, easiest way to navigate the night sky. This simple accessory attaches to the mounting bracket holes on virtually any telescope. Amateur astronomers love red dot finderscopes because they don't magnify the image, so you can look through the scope with both eyes and view an accurate depiction of the night sky in the optical window. Simply turn on the red dot and place it over your target, and the desired object is ready to view in a low power eyepiece.The first time you install your Star Pointer red dot finderscope, you'll need to align it to your telescope's main optics. This simple procedure takes just a couple of minutes and is best done during the day.

Celestron StarPointer Pro Reticle Finderscope - 51635

Celestron’s innovative new StarPointer Pro makes locating objects in the night sky easier and more comfortable than ever before. The ultra-wide 40mm optical window with 1x magnification is much more forgiving than a traditional red dot finderscope, allowing you to see the projection from a variety of angles and distances. Instead of a dot, StarPointer Pro features a dual circle reticle.This premium finderscope is an ideal complement to just about any telescope, from a large Dobsonian to a computerized Schmidt-Cassegrain. Mounting hardware is included to accommodate a variety of finderscope rails. Spend less time locating objects and more time enjoying them!A finderscope made for astronomyRed dot finders are a favorite among amateur astronomers, but these handy sights actually originated in airsoft. While a red dot is perfect for accurately placing your shot, it’s not the ideal marker for astronomy. If you’re trying to locate a small, faint, or fuzzy object, the red dot can completely cover or obscure your target, making it difficult to center with perfect accuracy.Enter the StarPointer Pro. Rather than covering up your target with a bright red dot, this reflex sight features two concentric circles. Once the finderscope is properly aligned, simply place your object inside the smallest circle, and you’ll have it dead center in your telescope’s eyepiece. Whether you’re observing the Moon and Venus during the day or under the darkest of dark skies, the StarPointer Pro can adapt to any environment thanks to its adjustable brightness LED.Starhopping made easy StarPointer Pro’s design goes beyond helping you locate bright celestial objects you can see. The concentric circles also serve as a measuring tool, helping you to “star hop” to dimmer objects. StarPointer Pro’s larger circle covers 2 degrees of the night sky; the smaller circle encompasses 1.2 degrees. If you’d like to locate an object 6 degrees away from a star you have centered in the StarPointer Pro, simply measure three of the larger circle lengths.

Celestron StarSense AutoAlign for Skywatcher SynScan - 94006

In 2013, Celestron revolutionized amateur astronomy with StarSense AutoAlign, a specialized accessory that allows your computerized telescope to align itself to the night sky with the push of a button. Now, that same technology comes to a variety of Sky-Watcher SynScan mounts.For the first time, Sky-Watcher owners can simply switch on their telescope and—in about three minutes—the mount is aligned and ready locate any object in the night sky. No more centering alignment stars in the eyepiece or adding GPS coordinates.Once the quick automatic alignment is complete, you can choose from thousands of objects to view or take a Sky Tour of the best objects currently visible. With StarSense, even first time users can harness the power of a computerized telescope.How Celestron’s patented StarSense technology worksStarSense AutoAlign is made up of two components that work together with your telescope: the camera and the StarSense hand control. The camera attaches to your telescope in place of a finderscope. (The mounting bracket is compatible with most Celestron and Sky-Watcher optical tubes.) The camera's wide field of view captures images of the star patterns overhead. Then, StarSense compares those images with its internal database of more than 40,000 celestial objects, matching up star patterns like fingerprints. Once a match is confirmed, StarSense calculates its exact position and the location of thousands of stars, nebulae, galaxies, and more.Your telescope just got smarterWith this handy accessory, a variety of Sky-Watcher mounts are now compatible with StarSense technology, including the AZ-EQ series of mounts. StarSense also works with Sky-Watcher's popular GoTo Dobsonians, taking your Dobsonian experience at star parties to the next level. Check out the product specifications for a full compatibility list.StarSense connects to your Sky-Watcher mount via a unique interface box. Use the 3 AUX ports and hand control port to connect the camera, hand control, and any other accessories you're using. Secure the interface box to the tripod leg via an included velcro strap.The most accurate GoTo alignment ever—perfect for astroimagingStarSense AutoAlign is fast and convenient for a night of casual stargazing.

Celestron Telescope UHC/LPR Filter - 2 Inch - 94124

Premium light-pollution killer!Celestron's 2-inch, ultra high-contrast, light pollution reduction (UHC/LPR) filter makes deep-sky observation and astrophotography possible in urban areas. That means you can capture stunning views of the Orion Nebula, the Rosette Nebula, the North American Nebula, the Veil Nebula the Helix Nebula, and many, many others from a nearby parking lot!Advanced TechnologyLPR filters work by reducing transmission of light wavelengths produced by artificial light. This includes mercury-vapor and both high- and low-pressure sodium-vapor lights. They also block "sky glow," or unwanted natural light, caused by neutral oxygen emission in our atmosphere.While blocking unwanted light, Celestron LPR Filters permit transmission of more desirable wavelengths, including those of hydrogen alpha, hydrogen beta, doubly ionized oxygen and singly ionized nitrogen. This will improve viewing of emission nebulae, both from urban and rural areas.This new, ultra high-contrast (UHC) LPR filter has improved contrast over the typical broadband filters. Sky background is darker, and contrast of emission nebulae is noticeably improved. Advanced-technology coatings enable the filter to achieve an outstanding transmission of more than 97 percent across the entire bandpass, with total blockage of prominent light pollution lines.Celestron's 2-inch UHC/LPR filter is the perfect accessory for viewing nebula from light-polluted skies, or for boosting the contrast of nebula from dark-sky sites. That makes it a must-have accessory for urban stargazers!

The Celestron TrailSeeker 100 45-Degree Spotting Scope offers huge optics with outstanding light-gathering capability and a whole lot more! You've seen the photographers who stand along the sidelines at a football game, right? Ever noticed how BIG their lenses are? They spend the money on large aperture optics because big lenses offer greater resolution in demanding light conditions, and everyone is hoping for the money shot.The Celestron 100mm TrailSeeker is a money shot spotting scope! With a diameter of almost 4 inches, you will notice brighter images in those tricky yet beautifully lit hours of dusk and dawn. Objects that disappear into the shade of a tree or the gathering gloom of deep shadow with smaller optics will pop into view with the TrailSeeker 100. Celestron's outstanding XLT coatings are applied in multiple layers to the optics to maximize light transmission and provide further increases in contrast, sharpness, and color rendition.Advanced features, such as an interchangeable zoom lens, rotatable tripod mount, and a dual focus mechanism are built into this well-designed spotting scope, and protection from dirt, dust, water and fogging are standard via the heavy-duty, rubber-armored, Nitrogen-purged body.Interchangeable zoom eyepieceThe Celestron TrailSeeker 100 comes with a high quality 22x - 67x zoom eyepiece. This magnification range is classic for a large 100mm spotting scope. It gives you a relatively low power, wide angle view at 22 times as far as your eye can see, and zooms up to 67x to really bring your subject in close. The 22x-67x zoom eyepiece is not built into the spotting scope itself, but is interchangeable, allowing you to add additional eyepieces to your repertoire of observing accessories.The TrailSeeker 22-67 zoom eyepiece offers good eye relief at both ends of the magnification range—18mm at 22x and 15mm at 67x—enough to enjoy a comfortable observing experience, even if you wear eyeglasses.Rugged waterproof, nitrogen-filled housingA good spotting scope should be able to accompany you in all sorts of weather, and the Celestron TrailSeeker 100 model is more than up to the task. The ruggedized, rubber-armored housing is purged of all moisture and then filled with Nitrogen. This procedure keeps water on the outside, where it belongs. No need to worry about rain, heavy dew, or for that matter, coffee, from penetrating into the optical housing or sensitive mechanical parts of the spotting scope. And what’s more, your optics will not fog in overly humid environments or when there is a large temperature change; the Nitrogen inside the TrailSeeker makes sure of that.The 52334 TrailSeeker model has an eyepiece housing that is angled 45 degrees. Whether you choose an angled or a straight body style is really personal preference. Many people prefer an angled eyepiece because the spotting scope and tripod can sit lower to the ground, making it more stable in windy conditions. The Celestron TrailSeeker spotting scopes all come with a rotatable tripod mount that allows you to position your eyepiece and focus knob right where you want it. If you prefer a straight spotting scope design, the TrailSeeker 52335 model is also available.Dual focus mechanism and sliding lens shadeTo cut glare and increase contrast, the Celestron 100mm TrailSeeker comes with a built-in, sliding lens shade. Just pull it forward when you need it, and push it back out of the way when you don’t. You will appreciate this feature when the sun is at your left or right, causing contrast-killing light to skip across your optics, and if it rains, the lens shade will keep water droplets off the glass, or at least delay it a bit.The dual focus mechanism on all Celestron TrailSeeker’s gives you two choices when it comes to focusing your spotting scope. Sometimes all it takes is a twist of the larger coarse focus knob, especially at lower powers. But when you are pushing your magnification to the max, you will really appreciate the ability to critically focus the image via the fine focus knob.

Celestron TrailSeeker Tripod with Fluid Pan Head - 82050

The Celestron TrailSeeker Tripod is lightweight yet sturdy, and comes with a fluid pan head for smooth movements in all directions. With a weight capacity of 8.8 pounds, fully adjustable legs, and multiple advanced features, the TrailSeeker Tripod is the perfect compliment to your spotting scope, binoculars, video camera, or DSLR. Fully adjustable tripod legsThe Celestron TrailSeeker Tripod comes with aluminum legs that are fully adjustable. They each have four telescoping sections that extend easily and lock into place with ergonomic flip levers. Drop each section down as needed, flip the lock lever closed, and move on to the next. The length of each tripod leg section can be adjusted anywhere along its length. The maximum height for the TrailSeeker Tripod is 58 inches without making use of the column extension, and 70.5 inches—almost 5 feet 9 inches!— if you extend the column fully. All three tripod legs are also adjustable when it comes to their angle position. This is a particularly nice feature if you find yourself setting up on ground that isn't perfectly flat. A release lever is located at the top of each tripod leg, allowing you to choose from three different leg locations. A bubble level on the top of the tripod will assist you in leveling your equipment as you make adjustments to the legs.Leg padding is easy on the shoulderMost people carry their tripod from place to place by slinging it over their shoulder. This can be uncomfortable without padding. Thanks to Celestron, two of the three tripod legs have cushioning wrapped around the uppermost section. This welcome feature also gives you a place to grab the tripod when working in cold conditions.Extendable column with retractable hookThe Celestron TrailSeeker Tripod comes with an extendable center column. This not only allows users to raise the height of the tripod past what the legs alone would allow, it provides a way to stabilize the tripod in windy conditions. How? Celestron added a retractable hook to the end of the column. Whenever you want extra stability, simply pull the hook into position and then hang something heavy on it. Anything will work, as long as it has some weight to it. Nature photographers often carry a bag with a handle or a string closure that can be used for this purpose, and then they put rocks, sand, or whatever else is lying nearby into the bag. When you don't need the hook, just push it back into the center column. Fluid pan head for smooth trackingThe two way fluid pan head, included with the TrailSeeker Tripod, makes it easy to smoothly follow moving objects. Simply grab the handle to pan the head up, down, right, or left, and then lock it in position with the head's oversized knob. There is also a bubble level on the side of the head to assist in keeping your equipment level. A quick release plate on the TrailSeeker pan head can be connected to the bottom of your spotting scope, camera, or small telescope for quick installation and removal.

Celestron UHC/LPR Telescope Filter - 1.25 Inch - 94123

Premium light-pollution killer!Celestron light pollution reduction (UHC/LPR) filters make deep-sky observation and astrophotography possible in urban areas. That means you can capture stunning views of the Orion Nebula, the Rosette Nebula, the North American Nebula, the Veil Nebula the Helix Nebula, and many, many others from a nearby parking lot!LPR filters work by reducing transmission of light wavelengths produced by artificial light. This includes mercury-vapor and both high- and low-pressure sodium-vapor lights. They also block "sky glow," or unwanted natural light, caused by neutral oxygen emission in our atmosphere.While blocking unwanted light, Celestron LPR Filters permit transmission of more desirable wavelengths, including those of hydrogen alpha, hydrogen beta, doubly ionized oxygen and singly ionized nitrogen. This will improve viewing of emission nebulae, both from urban and rural areas.This 1.25" ultra-high-contrast (UHC) LPR filter has improved contrast over the typical broadband filters. Sky background is darker, and contrast of emission nebulae is noticeably improved. Advanced-technology coatings enable the filter to achieve an outstanding transmission of more than 97 percent across the entire bandpass, with total blockage of prominent light pollution lines.Celestron's 1.25-inch UHC/LPR filter is the perfect accessory for viewing nebula from light-polluted skies, or for boosting the contrast of nebula from dark-sky sites. That makes it a must-have accessory for urban stargazers!

Coronado Personal Solar Telescope 1A Bandwidth - PST

The Coronado PST is a game-changing solar telescope. It’s the world’s most popular way to safely observe our closest star in Hydrogen-alpha light.Before the Coronado PST, observers could outfit their nighttime telescope with a suitable solar filter to view sunspots in white light, or they could spend thousands on dedicated solar scopes that display the Sun in brilliant red Hydrogen-alpha with stunning surface detail. With the PST, everyone can experience the magic of H-alpha solar observing, but at a fraction of the cost!This 40mm telescope features a bandpass of less than 1 angstrom, allowing only a tiny amount of H-alpha light to pass through to the eyepiece. A high quality milled aluminum—not plastic—housing prevents heat buildup inside the optical tube.The Sun is one of the most interesting celestial objects to observe thanks to its active and ever-changing surface. Despite its grab-and-go size, the PST will show you prominences, filaments, sunspots, and other interesting surface features. It’s also an amazing telescope to have on hand during a solar eclipse!Using the PST couldn’t be easier. The telescope body does not contain any moving or extending parts. Simply mount it on any photographic tripod, use the built-in Sol Ranger sunfinder to center the solar disk, adjust the built-in focuser, and begin observing! A 18mm Kellner eyepiece is included.The Coronado PST’s reusable box contains die-cut foam for storage. Optional accessories include a hard travel case, Malta tabletop mount, CEMAX series eyepieces, and the SolarMax 40 for double stacking and narrowing the bandpass. To add a SolarMax 40, you will nned the T-Max 40 for attaching the unit directly to the PST.Customers love the PST! “To be honest, I was not expecting too much, bearing in mind the cost and diminutive nature of the scope, but I finally set up in the late afternoon. Alignment of the scope is a breeze using the inbuilt sun finder. As I looked through the eyepiece, I could see a red sun with a small sunspot but no prominences or H-A detail and then decided to try the ‘tuner.’ As I rotated the ring, the view changed, prominences popped into view! With a little further ‘tweaking,’ filaments, faculae, and ‘orange peel’ surface came into view in incredible detail! Absolutely brilliant!” - Mr. N. Longshaw, U.K. “I purchased a PST a couple of months ago. After reading some comments on adding the SolarMax 40, I purchased one and attached it to the PST.

This "little" telescope is another step toward our goal of making it possible for everyone to, "Experience the Sun our way."Sub angstrom H-A systems have long been cost prohibitive for the amateur. Designs other than the Coronado are difficult to use because of temperature and F-Ratio requirements. Not only does the PST have a bandpass of <1.0 angstrom but it is also thermally stable and requires no more time to operate than putting in a eyepiece and adjusting the focus.The PST represents the same technology and quality that goes into a SolarMax series telescope but with a few unique design characteristics that allow us to offer it for less than some premium eyepieces. The PST will show you prominences, active regions, filaments, as well as other surface details - at <1.0 angstrom it will not reveal as much surface detail as the SolarMax series telescope and filters but it certainly doesn't disappoint."To be honest I was not expecting too much, bearing in mind the cost and diminutive nature of the scope, I finally set up in the late afternoon.

Coronado Sol Ranger - SOL

Coronado Sol Ranger FinderSun observers rave about Coronado's Sol Ranger-why? This excellent sun-finder can easily locate the Sun using any SolarMax telescope. Attach the Sol Ranger to the SolarMax telescope's clamshell mount and you are all set. A pinhole on the front of the Sol Ranger allows a harmless beam of light to be projected onto an opaque glass viewer when the sun is in the main scope's FOV. The resulting image can be viewed easily from the rear of the telescope - this ensures a rapid and accurate solar alignment process.

Explore Scientific 1.25&andquot; - 2x Focal Extender - FE02-125

Explore Scientific 2x Focal Extender - 1.25"The Explore Scientific 2x Focal Extender will boost the focal length of any 1.25" eyepiece to bring you excellent magnifications for visual observations or astro-imaging. The optics of the 2x Focal Extender are fully multi-coated using Explore Scientific's EMD enhanced coatings. All elements feature blackened edges to minimize reflections yet increase contrast for beautiful, clear views. By using a standard Barlow or tele-negative lens to enhance your optical system's magnification, the results you get will be reliant upon the placement of the Barlow in the optical chain. For example, if you place a 2x Barlow Lens in front of your diagonal instead of behind it (Barlow-Diagonal-Eyepiece as opposed to Diagonal-Barlow-Eyepiece), you won't achieve 2x magnifications in both configurations. Magnification differs with placement. However, with this Explore Scientific 2x Focal Extender, magnification is consistent even when the distance is altered. It can be placed anywhere in the optical chain between an eyepiece or a camera. 2x magnification means you will get 2x magnification. When it comes to imaging, this is a critical difference, because you may want to introduce an accessory like a flip mirror or filter wheel in between the Focal Extender and a CCD camera, which would increase the distance to the focused image. This difference in design allows users to rest easy, whether they are pumping up the magnification of a lower power eyepiece for visual observations or using their Explore Focal Extender in imaging applications.Explore Scientific Focal Extender Highlights More Magnification Choices without Sacrificing Eye ReliefA quality Focal Extender adds some genuine flexibility to your telescope accessory roster. First, it enables the magnification increase of any eyepiece you already own that has a barrel size identical to that of the focal extender. In other words, 3 eyepieces give you 6 magnification options with the addition of a focal extender. Second, lower magnification eyepieces usually have better eye relief than higher power models. By using a focal extender in lieu of a higher magnification eyepiece, you get to enjoy the comfortable eye relief of the lower power eyepiece. For observers who wear eyeglasses, or for those with fast telescopes who can really push high magnification eyepieces, this can be a significant perk. Optimized Optical DesignExplore Focal Extenders are optimized through each design, fabrication, and testing process to produce high contrast, high-resolution images. Durable Coatings &and Finishing TouchesAll four elements of Explore Scientific Focal Extenders are fully multi-coated using Explore EMD enhanced coatings for bright, sharp images. In addition, every element features blackened edges to minimize internal reflections and increase contrast. Tapered Barrel For Extra SecurityThe insert barrel of each extender is double-tapered to allow smooth insertion to, and removal from, a telescope's eyepiece holder, focuser or diagonal. However, the wide dimension of the taper helps prevent the focal extender from falling out of the telescope should the set-screw holding it in place become loose. The barrel is threaded to accept 1.25" filters.

Explore Scientific 100-Degree Eyepiece Kit with Case - EPWP100-KIT

Explore Scientific 100-Degree Eyepiece Kit The Explore Scientific 100-Degree Eyepiece kit includes a 5.5 mm, 9 mm, and 14 mm 100-Degree Argon-Purged Waterproof Eyepiece and a soft-sided case to ensure your eyepieces stay safe and clean. Each eyepiece is packaged individually in Explore Scientific's iconic Will Tirion star map box and includes caps for both ends. About Explore Scientific 100-Degree Eyepieces The Explore Scientific 100° Series™ eyepieces are hyper-wide class oculars that can transform your visual astronomy experience. You may be startled at the amazingly wide expanse of inky black sky you behold the first time you bring your eye to a 100° Series eyepiece, and after awhile, you may even forget that you have an eyepiece between you and the universe! With an apparent field of view that is close to the maximum for hyper-wide eyepiece design, objects are not only easier to locate, but for non-driven telescopes, the object will stay in the field of view for a very long time before any adjustments need to be made. Another great benefit of hyper-wide eyepieces is the ease with which you can gaze, not directly at an object, but slightly to either side. This skill, called using averted vision, is especially helpful when observing faint objects because using averted vision puts the image on a part of your eye that is more sensitive to light, allowing you to see fainter images. The Explore 100° Series eyepieces come with a removable and foldable soft silicone rubber eyecup for the comfort of the observer, and as experienced astronomers know, eye comfort is critical when trying to observe at the visual limits of the telescope. By making the eyepiece body Argon-purged, the eyepiece’s internal elements will remain as pristine as the day they were assembled. Argon atoms are “ larger” than that of Nitrogen and therefore they are less likely to “leak” or diffuse their way through the seals over the life of the eyepiece. The atomic radius of Argon is larger than Nitrogen by 0.13 angstroms and has a larger atomic volume by 11.2 cubic centimeters/molecule. Argon also has superior inertness vs Nitrogen (i.e. forming few or no chemical compounds with other elements) that prevents adverse reactions with eyepiece components and therefore extends the longevity of the internal components and also prevents chemical reactions with other elemental contaminants that may be introduced through a weakened seal. And finally, because Argon is less conductive than Nitrogen, Argon cools slower thereby buffering the effects of rapid temperature changes of the optics. The sealed, dry environment is impervious to internal fogging and contaminants such as fungus growing in between the lens elements. Explore Scientific’s waterproof eyepieces are easier to clean, and there is no risk of cleaning solution migrating from the top of the lens and seeping around the edges to be trapped in between elements. To ensure a perfect seal, Explore tests every eyepiece in one meter of water for 30 minutes. 5.5 mm SpecificationsFocal Length: 5.5 mmField of View: 100 degreesBarrel Size: 2"Coatings: EMDWaterproof: Yes, purged with Argon gas 9 mm SpecificationsFocal Length - 9 mmAFOV - 100 degreesEye Relief - 14.5 mmNitrogen-Purged and Waterproof: Submersible to 1 meter for 30 minutes; Internally sealed and purged with inert, dry nitrogen gas to prevent internal foggingCoatings - All lens-to-air surfaces are fully multi-coatedEyecups - Soft rubber folding style; ReplaceableWeight - 2 lb 14 mm SpecificationsFocal Length - 14 mmAFOV - 100 degreesEye Relief - 14.5 mmArgon-Purged and Waterproof: Submersible to 1 meter for 30 minutes; Internally sealed and purged with inert, dry argon gas to prevent internal foggingBody - Anodized Black Aluminum; Laser-Etched Description and Serial Number; Rubber Grip: Internally O-Ring SealedBarrel - Stainless-Steel, 2-inch, Double Taper, Accepts Standard 2-inch FiltersCoatings - All lens-to-air surfaces are fully multi-coatedEyecups - Soft rubber folding style; replaceableWeight - 2 lb All Explore Scientific telescope accessories are covered under their standard U.S.A.

The DAR102 comes with a 2" Dual-Speed Crayford Focuser, 8x50 Finderscope, and 2" Diagonal, while the FL-AR102 comes with a 1.25" Diagonal, Red Dot Finder, and 40 mm Draw Tube Focuser.Optics, Optics, Optics!The optics in their collimatable lens cell are fully multi-coated to eliminate light scatter and maintain image contrast. We precision collimate every Explore Scientific telescope at our factory to give optimum performance. Although you may never need to adjust optical alignment, the AR Series allows for collimating the lens set should the telescope ever require it. Contrast is further enhanced with multiple baffles that mask and deflect unwanted stray light. The Focuser:The Explore Scientific Air-Spaced Doublet AR Series telescopes include a precision 2-inch two-speed focuser as standard equipment. The eyepiece holder uses a compression ring to prevent the eyepiece or camera barrel from scoring. Many telescopes are only supplied with a standard single-speed focuser, you will find that a tiny nudge will throw out focus and turn your night into one of frustration. So we included as standard equipment, on all Explore Scientific AR Series, a two-speed Crayford-style precision focuser with tension adjustment and a lock, to obtain and hold perfect focus. We think you'll agree that such precision is worth it. The Diagonal:The Two-Inch Dielectric Diagonal includes a 1.25" eyepiece holder adapter and dust covers to protect the mirror. Provided as standard equipment, Explore Scientific's Two Inch Dielectric Diagonal incorporates a light-weight, one-piece diagonal body that securely cradles the precision polished diagonal flat mirror, insuring precision alignment. Ultra-high reflective coatings (99% reflective) composed of multiple thin layers of dielectric material delivers maximum light output.Both 2" and 1.25" eyepiece holders use compression rings instead of a simple set-screw to more securely hold your valued eyepiece (or imaging device) and to minimize scoring of eyepiece barrels. You can thread standard 48 mm filters into the barrel.The Finder:The Explore Scientific 8x50 Finder Scope provides a true field of view of 6 degrees. Its coated optics provide a bright high-resolution image so that many faint stars and nebulosity can be detected, for precise aiming of your scope.

Enjoy the picturesque wide expanse of inky black sky you will see in the 92° Series eyepiece. With non-driven telescopes, you will benefit from viewing objects that stay in the field of view for a long time before any adjustments are necessary. The Explore 12mm 92º Eyepiece has nearly 20mm of eye relief. This Explore Scientific eyepiece is designed to increase the comfort level for long nights of observing as well as give you an amazingly immersive visual experience.Another great benefit of hyper-wide eyepieces is the ease with which you can gaze, not directly at an object, but slightly to either side. This skill, called using averted vision, is especially helpful when observing faint objects because using averted vision puts the image on a part of your eye that is more sensitive to light, allowing you to see fainter images.The Explore 92° Series eyepieces come with a removable and foldable soft silicone rubber eyecup for the comfort of the observer, and as experienced astronomers know, eye comfort is critical when trying to observe at the visual limits of the telescope.By making the eyepiece body Argon-purged, the eyepiece’s internal elements will remain as pristine as the day they were assembled. Argon atoms are “ larger” than that of Nitrogen and therefore they are less likely to “leak” or diffuse their way through the seals over the life of the eyepiece. The atomic radius of Argon is larger than Nitrogen by 0.13 angstroms and has a larger atomic volume by 11.2 cubic centimeters/molecule. Argon also has superior inertness vs Nitrogen (i.e. forming few or no chemical compounds with other elements) that prevents adverse reactions with eyepiece components and therefore extends the longevity of the internal components and also prevents chemical reactions with other elemental contaminants that may be introduced through a weakened seal. And finally, because Argon is less conductive than Nitrogen, Argon cools slower thereby buffering the effects of rapid temperature changes of the optics.The sealed, dry environment is impervious to internal fogging and contaminants such as fungus growing in between the lens elements. Explore Scientific’s waterproof eyepieces are easier to clean, and there is no risk of cleaning solution migrating from the top of the lens and seeping around the edges to be trapped in between elements. To ensure a perfect seal, Explore tests every eyepiece in one meter of water for 30 minutes.

Argon also has superior inertness vs Nitrogen (i.e. forming few or no chemical compounds with other elements) that prevents adverse reactions with eyepiece components and therefore extends the longevity of the internal components and also prevents chemical reactions with other elemental contaminants that may be introduced through a weakened seal. And finally, because Argon is less conductive than Nitrogen, Argon cools slower thereby buffering the effects of rapid temperature changes of the optics.The sealed, dry environment is impervious to internal fogging and contaminants such as fungus growing in between the lens elements. Explore Scientific’s waterproof eyepieces are easier to clean, and there is no risk of cleaning solution migrating from the top of the lens and seeping around the edges to be trapped in between elements. To ensure a perfect seal, Explore tests every eyepiece in one meter of water for 30 minutes.

Explore Scientific 2" 2x Focal Extender - FE02-020

Explore Scientific 2x Focal Extender - 2"The Explore Scientific 2x Focal Extender will extend the focal length of any 2" eyepiece to bring you fantastic magnifications for astro-imaging or visual observations. The optics of the 2x Focal Extender are fully multi-coated using Explore Scientific's EMD enhanced coatings. All elements feature blackened edges to minimize reflections yet increase contrast for beautiful, clear views. By using a standard Barlow or tele-negative lens to enhance your optical system's magnification, the results you get will be reliant upon the placement of the Barlow in the optical chain. For example, if you place a 2x Barlow Lens in front of your diagonal instead of behind it (Barlow-Diagonal-Eyepiece as opposed to Diagonal-Barlow-Eyepiece), you won't achieve 2x magnifications in both configurations. Magnification differs with placement. However, with this Explore Scientific 2x Focal Extender, magnification is consistent even when the distance is altered. It can be placed anywhere in the optical chain between an eyepiece or a camera. 2x magnification means you will get 2x magnification. When it comes to imaging, this is a critical difference, because you may want to introduce an accessory like a flip mirror or filter wheel in between the Focal Extender and a CCD camera, which would increase the distance to the focused image. This difference in design allows users to rest easy, whether they are pumping up the magnification of a lower power eyepiece for visual observations or using their Explore Focal Extender in imaging applications.Explore Scientific Focal Extender Highlights More Magnification Choices without Sacrificing Eye ReliefA quality Focal Extender adds some genuine flexibility to your telescope accessory roster. First, it enables the magnification increase of any eyepiece you already own that has a barrel size identical to that of the focal extender. In other words, 3 eyepieces give you 6 magnification options with the addition of a focal extender. Second, lower magnification eyepieces usually have better eye relief than higher power models. By using a focal extender in lieu of a higher magnification eyepiece, you get to enjoy the comfortable eye relief of the lower power eyepiece. For observers who wear eyeglasses, or for those with fast telescopes who can really push high magnification eyepieces, this can be a significant perk. Optimized Optical DesignExplore Focal Extenders are optimized through each design, fabrication, and testing process to produce high contrast, high-resolution images. Durable Coatings &and Finishing TouchesAll four elements of Explore Scientific Focal Extenders are fully multi-coated using Explore EMD enhanced coatings for bright, sharp images. In addition, every element features blackened edges to minimize internal reflections and increase contrast. Tapered Barrel For Extra SecurityThe insert barrel of each extender is double-tapered to allow smooth insertion to, and removal from, a telescope's eyepiece holder, focuser or diagonal. However, the wide dimension of the taper helps prevent the focal extender from falling out of the telescope should the set-screw holding it in place become loose. The barrel is threaded to accept 2" filters.

Explore Scientific 2" 3x Focal Extender - FE03-020

Explore Scientific 30 mm 100° Waterproof 3" EyepieceThe 30mm 100° Series™ eyepiece by Explore Scientific is part of an ultra-wide class of oculars that will revolutionize your astronomy observations. Enjoy the picturesque wide expanse of inky black sky you will see in the 100° Series eyepiece. The Explore 30mm 100º Eyepiece has nearly 20mm of eye relief. This Explore Scientific eyepiece is designed to increase the comfort level for long nights of observing as well as give you an amazingly immersive visual experience. Another great benefit of hyper-wide eyepieces is the ease with which you can gaze, not directly at an object, but slightly to either side. This skill, called using averted vision, is especially helpful when observing faint objects because using averted vision puts the image on a part of your eye that is more sensitive to light, allowing you to see fainter images. Explore Scientific 100° Eyepiece HighlightsHuge 3" Barrel for Amazing Light Throughout: The Explore Scientific 30mm 100° Eyepiece has a 3" barrel for use in today's over-sized focusers. The eye relief is a comfortable 19mm, and the field stop diameter is 52.2mm. This eyepiece weighs 82.9 ounces and is 7.8" tall.Optimized Optical Design: Explore 100° Series hyper-wide eyepieces are optimized through each design, fabrication, and testing process to produce flat-field images that have high contrast and resolution.Exotic Glass Combinations for Optimum Results: Eyepieces are constructed of 8 or 9 lens elements (depending on the focal length) that are fabricated from combinations of Dense Crown, Light Crown, Dense Flint, and Lanthanum optical glass.Durable Coatings &and Finishing Touches: Each element in your Explore Scientific 100° eyepiece features EMD coatings, resulting in bright, sharp images, and every element has blackened edges to reduce internal reflections and increase contrast.Waterproof, Fog-Proof Housing: The internal optics of all 100° Series eyepieces are housed in an argon-purged, waterproof barrel that keeps them as pristine as the day they were manufactured. Cleaning is much easier, and there is no need to worry about water or fluid becoming trapped in between elements due to rain, spills, heavy dew, or getting over-enthusiastic with lens cleaning fluid.Hyper-Wide Field Experience: The 100° experience is different than that of more conventional eyepieces. A hyper-wide field of view means you can see more of the night sky at once, allowing you to observe larger or closer objects in their entirety, or to easily use inverted vision to capture faint photons of light. Also, those using Dobsonians or other instruments without a motor drive will enjoy watching an object drift more slowly across the field of view. Manually moving your telescope to compensate for the rotation of the Earth will be required much less frequently, and that's a good thing.Tapered 3" Barrel for Extra Security: The 3" insert barrel of the 30mm eyepiece is double-tapered to allow smooth insertion to, and removal from, a telescope's focus, however the wide dimension of the taper helps prevent the eyepiece from falling out of the telescope should the set-screw holding it in place become loose. Explore Scientific backs each eyepiece with the Explore STAR Transferrable, Extended Life of the Product Warranty (life of the product line plus five years!), so you can keep exploring!

Enjoy a fully immersive experience with generous eye relief and high-contrast, high-resolution views with this 68º Series eyepiece.By making this Explore Scientific eyepiece body Argon-purged, the waterproof eyepiece internal elements will remain as pristine as the day they were assembled. Argon atoms are “ larger” than that of Nitrogen and therefore they are less likely to “leak” or diffuse their way through the seals over the life of the eyepiece. The atomic radius of Argon is larger than Nitrogen by 0.13 angstroms and has a larger atomic volume by 11.2 cubic centimeters/molecule. Argon also has superior inertness vs Nitrogen (i.e. forming few or no chemical compounds with other elements) that prevents adverse reactions with eyepiece components and therefore extends the longevity of the internal components, and also prevents chemical reactions with other elemental contaminants that may be introduced through a weakened seal. And, finally, because Argon is less conductive than Nitrogen, Argon cools slower thereby buffering the effects of rapid temperature changes of the optics. The sealed, dry environment is impervious to internal fogging and contaminants such as fungus growing in between the lens elements. Our waterproof eyepiece is easier to clean, and there is no risk of cleaning solution migrating from the top of the lens and seeping around edges to be trapped in between elements. To ensure a perfect seal, Explore tests every eyepiece in one meter of water for 30 minutes.

About Explore Scientific 82-Degree Eyepieces Explore Scientific 82° Series™ eyepieces, with their 82° apparent field of view, immerses you in a very comfortable ultra-wide field that naturally promotes relaxation at the eyepiece.

The atomic radius of Argon is larger than Nitrogen by 0.13 angstroms and has a larger atomic volume by 11.2 cubic centimeters/molecule. Argon also has superior inertness vs Nitrogen (i.e. forming few or no chemical compounds with other elements) that prevents adverse reactions with eyepiece components and therefore extends the longevity of the internal components and also prevents chemical reactions with other elemental contaminants that may be introduced through a weakened seal. And finally, because Argon is less conductive than Nitrogen, Argon cools slower thereby buffering the effects of rapid temperature changes of the optics. The sealed, dry environment is impervious to internal fogging and contaminants such as fungus growing in between the lens elements. Explore Scientific’s waterproof eyepieces are easier to clean, and there is no risk of cleaning solution migrating from the top of the lens and seeping around the edges to be trapped in between elements. To ensure a perfect seal, Explore tests every eyepiece in one meter of water for 30 minutes. 6.7 mm SpecificationsFocal Length - 6.7 mmBarrel Size - 1.25"Eye Relief - 15.7 mmElements - 7 in 4 GroupsParfocal - YesArgon-purged and waterproof - YesWeight - 8 oz 11 mm SpecificationsFocal Length - 11 mmBarrel Size - 1.25"Eye Relief - 15.6 mmElements - 7 in 4 GroupsParfocal - YesNitrogen-purged and waterproof - YesWeight - 9.8 oz 18 mm SpecificationsFocal Length - 18 mmBarrel Size - 2"Eye Relief - 13 mmElements - 6 in 4 GroupsParfocal - YesArgon-purged and waterproof - YesWeight - 13.7 oz 30 mm SpecificationsFocal Length - 30 mmBarrel Size - 2"Eye Relief - 22 mmElements - 6 in 4 GroupsParfocal - YesArgon-purged and waterproof - YesWeight - 35.5 oz All Explore Scientific telescope accessories are covered under their standard U.S.A.
