About the Celestron CPC 925 GPS (XLT) Computerized Telescope...
The CPC 925 GPS XLT is one of Celestron'''s top-of-the-line fork-mounted astronomical telescopes and includes Celestron'''s premium StarBright XLT coatings. This Celestron Telescope is at home as a superb visual instrument or, with optional wedge and Celestron CCD Cameras, as a serious astrophotographer'''s tool. Turn the Celestron CPC 925 GPS (XLT) Computerized Telescope towards planets and see amazing detail on the surface of Jupiter; 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. Hundreds of deep space objects are also visible.
Although large in aperture, with its conveniently located carrying handles and an instrument weight of only 58 lb., the Celestron CPC 925 GPS (XLT) Computerized Telescope is portable enough to set up in your backyard or take with you to your favorite dark sky location. The Celestron CPC telescopes, like their acclaimed Advanced Series and premium CGE Series Celestron Telescope, feature meticulously matched and hand-figured optical systems. In addition, all CPC models are diffraction limited and come standard with 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 Celestron Telescope family that provides superior quality, unsurpassed ease of use, and incomparable value.
The Celestron CPC 925 GPS (XLT) Computerized Telescope use an internal GPS receiver that 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. Once the internal GPS has established the Celestron CPC'''s position, aligning the telescope is as easy as 1-2-3! Simply use the Celestron Telescope CPC 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 your Celestron CPC Telescope is aligned, the remote hand control allows direct access to each of the celestial catalogs in its user-friendly database.
The Celestron CPC 925 GPS (XLT) Computerized Telescope database contains over 40,000 celestial objects including Messier objects and 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). The Identify feature tells you what you'''re looking at with your CPC Celestron Telescope, 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 is also a "Solar Sys Align" feature that lets you align your CPC Celestron Telescope on the sun or moon for daytime observing - it is easy to use this feature to see planets or bright stars in the day.
