Experience advanced astronomical performance with the Celestron CGX 800 HD, combining Celestron's powerful CGX computerized equatorial mount with the acclaimed EdgeHD optical system. Designed for serious visual observation and astrophotography, this telescope delivers a compelling balance of optical performance, portability, and advanced computerized control. With 8 inches of aperture, the CGX 800 HD gathers dramatically more light than the unaided eye, providing brighter and more detailed views of celestial objects. Its premium StarBright XLT coatings further enhance light transmission through the optical system, helping maximize the performance of the EdgeHD optics. The combination of EdgeHD optics and the CGX computerized equatorial mount creates a capable platform for exploring the night sky. Despite its advanced capabilities, the CGX 800 HD is designed to remain the lightest and most portable telescope in its class, making it an excellent choice for astronomers who want serious performance without sacrificing mobility.

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 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.
