    The CGX 800 Schmidt-Cassegrain Telescope features Celestron’s premium StarBright XLT coated optics and the all-new state of the art CGX computerized equatorial mount. It is the most lightweight and portable of the three size models. This telescope is especially at home as a solid platform for long exposure photography with optional CCD cameras or photographic equipment. At 8 inches of aperture with our premium StarBright XLT coatings, the CGX 800 gives you over 800 times the light gathering power than the unaided eye.

    CGX Mount

    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 all-new CGX EQ, a culmination of all the advancements made to our technologies, value, and ease-of-use.

    The new 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 new Equatorial backbone to support a wide range of telescopes.
