Celestron's CGX Equatorial 1100 SCT combines the innovative CGX computerized equatorial mount with its premium StarBright XLT coated optics.

With the optical tube assembly (OTA) weighing only 12.4kg, this telescope is a great companion for trips. This CGX instrument has 89% more light-gathering power than an 8" telescope and 40% more than a 9.25". For astrophotography, the CGX mount offers a sturdier platform with a smoother, heavy-duty belt drive system. It also features advanced software and new electronic and ergonomic features for the best starry night adventures! 

CGX Mount and Tripod Features | Improved Performance:

The new CGX was designed to better support your telescope for both visual and astro-imaging pursuits. It is Celestron's new equatorial backbone to support a wide range of telescopes.
