Celestron CPC 800 GPS XLT Computerized Telescope

The Celestron CPC 800 XLT Schmidt-Cassegrain Telescope 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.

The perfect mix of portability and large aperture size

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 CPC Telescopes are available in three aperture size choices:

* 8 Inch CPC Schmidt-Cassegrain Telescope
* 9.25 Inch CPC Schmidt-Cassegrain Telescope
* 11 Inch CPC Schmidt-Cassegrain Telescope

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.

Internal GPS

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 Sys Align" that 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.

Innovative Features

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.

With the introduction of the CPC Series, Celestron has “gone back to the drawing board” and re-designed, re-engineered, and re-invented a telescope family that provides superior quality, unsurpassed ease of use, and incomparable value. All CPC models ship standard with our NexRemote telescope control software.

Easy to use, align. Control by other software. - Review by
Overall Score
I've had this Celestron for just over a year. I was contemplating getting a Meade LX90 or LX200 but was talked into getting a Celestron CPC800 instead. I've had no regrets.
The CPC800 is easy to set up, align and use. It has a solid tripod. Images look good to me, but I dont really have anything else to compare it with because I dont own another telescope.
Although it took me some time to learn how to use and align the GPS system, it never fails. The control menu is also not too complex.
I have used it with the Starry Night software which has given no problems. The same goes for the SkyFi and Sky Voyager systems.
I am very happy with it.
But before you buy, check up Meade Light Switch technology, Meade LX8 LS.

I am looking for a gift for my partner - he is a gadget freak but I don't know anything about telescopes. We are moving to the beach and he wants a telescope to view boats on the horizon as well as looking at the stars/planets. Is the Celestron 9.25 inch good for both of these?
The Cassegrains will all be good for both land viewing and astronomy. However you'll just need an erect image diagonal (http://www.ozscopes.com.au/celestron-erect-image-diagonal-45-degree-94112-a.html) to flip the image the right way up for land viewing because they're naturally flipped upside down and left to right (which doesn't make a difference in astronomy). For the CPC800 and CPC925, their lowest useful magnification is 29x and 34x respectively, so it'll be good for looking really far out onto the horizon, depending on how far your house will be from the horizon.
Do you have a wedge for my CPC800, for CCD imaging? Is this the best option? Or a new equtorial-mount tripod? Prices?
Yes there is a wedge for CPCs to position the scope at to reach certain angles. The RRP for them in Australia is $999 and if you are interested and our price would be $899.
Can I hook a Celestron 8 inch CPC 800 xlt to an iPad and record viewings?
Unfortunately, there isn't any kit that is compatible with the iPad that will allow it to hook onto the telescope to record viewings. There is, however, a Celestron camera which will fit the telescope eyepiece and be able to record videos onto your computer. You can view a description of this camera here: http://www.ozscopes.com.au/celestron-neximage-solar-system-imaging-kit.html .
