The Celestron CGX 1100 Schmidt-Cassegrain Telescope features Celestron’s premium StarBright XLT coated optics and the state of the art CGX computerized equatorial mount. With the optical tube assembly of the CGX 1100 weighing only 27.5 lb., this telescope is still portable enough to be taken to dark skies, and it has 89% more light gathering power than an 8″ telescope and more than 40% more than the 9.25″.
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.
