The Celestron CGX 800 Schmidt-Cassegrain Telescope combines an advanced 8-inch optical system with Celestron’s computerized CGX equatorial mount to deliver a powerful and versatile platform for visual astronomy and astrophotography. Featuring Celestron’s premium StarBright XLT coated optics, the CGX 800 is designed to provide excellent light-gathering performance and a strong foundation for detailed observations and imaging. As the lightest and most portable model in the three-size CGX series, the CGX 800 offers an excellent balance of optical performance and portability. Its compact, manageable design makes it especially well suited for astronomers who want the capabilities of a computerized equatorial mount while maintaining greater ease of transport. The CGX 800 is also particularly well suited as a stable platform for long-exposure astrophotography. With support for optional CCD cameras and photographic equipment, the computerized equatorial mount provides a solid foundation for capturing detailed astronomical images. With its 8-inch aperture and premium StarBright XLT coatings, the CGX 800 delivers more than 800 times the light-gathering power of the unaided human eye, opening up a wealth of celestial targets for exploration and imaging.

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.
