Celestron Power Tank 7A 12V Power Supply - 18774
The CPC 800 GPS XLT is the most portable of Celestron's top-of-the-line fork-mounted astronomical telescopes and includes Celestron's premium StarBright XLT coatings. This telescope is at home as a superb visual instrument or, with optional wedge and CCD cameras, as a serious astrophotographer's tool. Turn this scope to planets and see amazing detail on the surface of Jupiter; see Cassini's Division in the rings of Saturn, and resolve details on the surface of Mars. Even the distant Uranus, Neptune and Pluto are within your reach.
Although large in aperture, with its conveniently located carrying handles and an instrument weight of only 42 lb., this telescope is portable enough to setup in your backyard or take with you to your favorite dark sky location.
Celestron's new CPC Series with revolutionary SkyAlign Alignment
Technology re-defines everything that amateur astronomers are looking for — quick and simple alignment, GPS, unsurpassed optical quality, ease of set-up and use, ergonomics, enhanced computerization and, most important, affordability.
The CPC Series' internal GPS receiver automatically downloads the date and time from orbiting satellites and pinpoints its exact location on Earth. This eliminates the need for you to manually enter the date, time, longitude and latitude.
Celestron's Revolutionary SkyAlign
Once the CPC's internal GPS has established the telescope's position, aligning the telescope is as easy as 1-2-3! Simply locate and use hand control to manually point (slew) the telescope to three bright celestial objects. You do not need to know the names of the stars — you may even pick the moon or bright planets! Celestron's NexStar® software technology will model the night sky to determine the position of every star, planet and celestial object above the horizon. Once aligned, the remote hand control allows direct access to each of the celestial catalogs in its user-friendly database.
Celestial Object Database
The CPC database contains over 40,000 celestial objects including Messier objects, the Caldwell Catalog, as well as NGC galaxies, nebulae and planets. User-definable filter limits make navigating through this expansive database quicker and easier. Filter Limits let you filter out objects that are outside of your local horizon (ie, if trees or mountains were in the way).
Identify feature tells you what you're looking at, but it can also be a very fun way to tour around the sky. Just point the telescope up somewhere and ask it to identify Messier objects (for instance) and it will show you the 5 nearest Messier objects to your position and let you GOTO them. You can keep doing this for different parts of the sky or for different object types -- it is a lot of fun.
There's also "Solar System Align," which lets you align on the sun or moon for daytime observing; it is easy to use this to see planets or bright stars in the day.
The new CPC Series telescopes, like our acclaimed Advanced Series and premium CGE Series telescopes feature meticulously matched and hand-figured optical systems that are manufactured in our facilities in Torrance, California. In addition, all CPC models are available with StarBright and StarBright XLT High Performance Optical Coatings.

Powering your Celestron CPC Telescope
The Celestron CPC Series Telescopes include a DC power cable, the kind you can plug into a automobile cigarette lighter. The CPC series telescopes do not take batteries. Won't take batteries! What! Actually this is a good thing. These larger telescopes eat through batteries pretty quickly. Its best to have a more reliable power source.
Astrophotography with the Celestron CPC Telescopes
While astrophotography could not be summed up here in one paragraph, a very common question for the CPC telescopes is how to connect a camera to it. Astrophotography is a hobby of patience and lots of trial and error, and plenty of errors will be had once you get started. But the rewards of good images is well worth it.
The 8 Inch CPC Telescope includes a 40mm Plossl Eyepiece. The 8 Inch CPC focal length is 2032mm so this included eyepiece will yield you 51x magnification. To get the most from your new CPC Telescope, we recommend you have a wide selection of eyepieces for high power viewing as well as wide-field viewing. TThis kit includes five 1.25 inch format eyepieces to give you the following magnification ranges in the 2032mm focal length 8 inch CPC Telescope:
- 4mm (508x Magnification)
- 6mm (339x Magnification)
- 9mm (226x Magnification)
- 15mm (135x Magnification)
- 32mm (64x Magnification)
This wider array of eyepieces will enhance your viewing of lunar and planetary surfaces. Select the Celestron Eyepiece and Filter Kit - 1.25 Inch Format as a great starter accessory for getting the most of your new Celestron 8 Inch CPC Telescope.
Upgrade to a 2 Inch Diagonal and 2 Inch format Eyepieces
2 Inch Format Eyepieces will deliver a wider field of view. Instead of only having the Andromeda Galaxy in your field of view, now you can also have the same view but with its surroundings. A 2-Inch format eyepiece also gives the feeling of "spacewalking" into the view. Your eyes see substantially more field of view and many find that the 2 inch format eyepieces are more comfortable to view into.
Before you can use a 2 inch format eyepiece on the 8 inch CPC telescope, you must upgrade the 1.25 inch format diagonal that is included with the telescope. By changing to a larger 2 inch format diagonal you are now able to use 2 inch format eyepieces. Most 2 inch format diagonals also include a "reducer" adapter that will continue to allow you to use your 1.25 inch format eyepieces.
Upgraded Diagonal, now select some premium 2 inch format eyepieces
Its common to hear that your telescope is only as good as your eyepiece. The eyepiece is how you deliver the image your telescope has gathered to your eye. A quality eyepiece can mean the difference of seeing major amounts of detail.
Power Adapters and Power Sources
The Celestron CPC telescopes include a car battery adapter power cord for powering your telescope through your vehicle.
The Celestron PowerTank will give you many nights of viewing with your CPC telescope on one single charge. This rechargeable battery can be used over and over and even includes a powerful spotlight for cleanup and tear-down of your equipment. No more lost accessories left out overnight! The PowerTank is the best choice for powering your CPC telescope and is very convenient.

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. 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 8 Inch CPC Telescope
Dew 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.
