The Celestron CGX 1100 Schmidt-Cassegrain Telescope combines Celestron’s premium StarBright XLT coated optics with the advanced CGX computerized equatorial mount, delivering powerful optical performance in a package that remains practical to transport. Designed for astronomers who want greater light-gathering capability without giving up portability, the CGX 1100 is an excellent choice for both detailed observation and astrophotography. Its 11-inch optical tube assembly weighs just 27.5 lb, making the CGX 1100 surprisingly portable for a telescope of its aperture. This allows you to take advantage of darker skies away from city light pollution without the challenges typically associated with transporting larger optical systems. The 11-inch aperture also provides a significant increase in light-gathering performance. Compared with an 8-inch telescope, the CGX 1100 collects 89% more light, while providing more than 40% greater light-gathering power than a 9.25-inch telescope. Combined with Celestron’s StarBright XLT optical coatings, this larger aperture provides an impressive platform for exploring a wide range of celestial targets.

Celestron’s workhorse CGEM mount lineup has been the German Equatorial backbone for telescopes ranging from 6 to 11 inches of aperture. Since that time, many more astro-imagers and planetarium controlled setups have emerged as backyard telescope technology has evolved. Celestron’s engineering team applied their years of experience designing German Equatorial mounts to the CGX EQ, a culmination of all the advancements made to our technologies, value, and ease-of-use. The CGX was designed to better support your telescope for both visual and astro-imaging pursuits. Key design goals included a lower profile EQ head, which provides a more compact and therefore more stable setup; a better drive system; remote operation-friendly with home and limit optical sensors; easier polar alignment adjustments; and better cable management. In addition to that, we’ve made mechanical and ergonomic improvements throughout to make the mount sturdier, easier to use, and transport. The CGX is our Equatorial backbone to support a wide range of telescopes.
