About the Celestron C10-NGT Advanced Computer Telescope - 10" Reflector w/GoTo Mount...The popular 10" Newtonian in the Celestron Advanced series is now available on the heavy-duty CG-5 computerized mount. The Celestron C10-NGT Newtonian scope uses diffraction-limited parabolic primary mirror for razor sharp star images across a wide field of view. The optics of these heavy-duty telescopes are manufactured to Celestron''s uncompromising standards with star images that are classic textbook Airy disks. Mounted on the Celestron Advanced GT Series Computerized Mount, this telescope has some high performance software and hardware features. Operated by proven NexStar computer control technology, the telescope has a 40,000+ object database with 100 user-definable objects and expanded information on over 200 objects. Custom database lists of all the most famous deep-sky objects by name and catalog number; the most beautiful double, triple and quadruple stars; variable stars; solar system objects and asterisms. Using the RS-232 communication port on the hand control, you can control the Celestron C10-NGT via a personal computer, and the new flash upgradeable hand control allow you to update your telescope''s operating software via the Internet. An Autoguider port is also included for astrophotography. No matter at what level you are starting out, this precision instrument will satisfy your needs both visually and photographically. The new German Equatorial mount has precision worm gears on both axes for extremely smooth stability. The key element that makes this system the most stable in its class is the heavy-duty tripod with larger and more substantial legs that offer excellent damping characteristics for more stable views. The Celestron C10-NGT also has a convenient latitude scale for easier alignment and an optional polar finder scope for the ultimate in precision alignments.
