The pinnacle of Celestron ED Scopes, Celestron C100 ED R-GT Computerized Telescope 21027 is packed with great features and excellent optics. The refractor style of Celestron 100ED (APO) Telescopes features a 2" rack and pinion focuser and has a bracket that can adapt to a photo tripod.

Celestron ED Glass provides excellent color correction and razor sharp images and virtually eliminates chromatic aberration usually seen during planetary and lunar viewing. C100ED-RGT Celestron 4" Computerized Telescope 21027 comes complete with a 25mm 1.25" eyepiece, erect image diagonal and 6x30 finderscope.

Celestron C100 ED R-GT Computerized Telescope 21027 is GT versions of Celestron 100 mm Advanced Series Telescope on a Computerized Go To version of Celestron CG-5 mount. Couple solidly-built Celestron CG-5 German Equatorial Mount with the included Celestron NexStar Computerized Control System to utilize many of the same functions and features as most advanced Celestron Go To Telescopes .

Celestron CG 5 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 NEW Heavy-Duty Tripod with larger and more substantial legs that offer excellent damping characteristics for more stable views. Celestron CG-5 Mount also has a convenient latitude scale for easier alignment and an optional polar finder scope for the ultimate in precision alignments.

Celestron 100 mm Computerized GoTo Telescopes are also upgradeable to GPS with the optionalCelestron CN16 GPS Accessory (# 93966) allowing Celestron C 100 ED R GT Telescope to pinpoint your position on the earth, the date and time, making the alignment process faster and easier than ever before!

Celestron C100ED RGT 4" GO TO versions of Celestron 100 mm Advanced Refractor Telescopes also come loaded with new software features and over 40,000 database objects .
