The CGX 800 HD combines Celestron's EdgeHD 800 optical tube with the CGX German equatorial mount. 

Celestron CGX 800 HD combines Celestron's all-new state of the art CGX computerized equatorial mount with its established and acclaimed EdgeHD optical system. With 8 inches of aperture and our premium StarBright XLT coatings, the CGX 800 HD gives you over 800 times the light gathering power than the unaided eye and is the lightest and most portable telescope in its class.

SeeThe Universe in HD

The EdgeHD is an aplanatic, flat field Schmidt-Cassegrain telescope that produces aberration-free images across a wide visual and photographic field of view. The optical system was designed to reduce more than just off-axis star coma; it also provides an astrograph-quality flat focal plane all the way to the edge of the field of view. In practical terms, stars appear more like pinpoints across the entire field. Many optical designs that advertise themselves as "astrographs" actually only produce pinpoint stars across a curved focal plane. While this may be acceptable for some visual observing, stars will appear out of focus at the edge when used with the flat chip sensor of a digital camera. EdgeHD optics produce a focal plane more than three-times flatter than a standard Schmidt-Cassegrain telescope and dramatically flatter than competing coma-free designs. This guarantees you visibly sharp stars across some of the largest CCD chips available today.

Improved Performance

Superior edge performance not only creates rounder, more pleasing stars, but actually improves the resolution and limiting magnitude when compared to telescopes of equal aperture. With Celestron’s StarBright XLT optical coatings on every surface, EdgeHD optics gives you maximum light throughput across the widest visual and photographic spectrum. Every EdgeHD that ships has been tested not only for the surface quality of each optical component, but also with a camera and artificial star to ensure the imaging system meets our rigid quality assurance. This “final acceptance test” confirms the EdgeHD will perform in the field and deliver high-quality astroimages.

Fastar Versatility

EdgeHD is the most versatile imaging telescope available today. At its native f/10, you can achieve the image scale necessary to capture the smallest of deep sky objects. Add the optional 0.7x reducer lens—custom-designed for your size EdgeHD tube—and you can increase your field of view without sacrificing optical performance. Add a Barlow or image amplifier to increase focal length even further for planetary imaging. All EdgeHD optical tubes are Fastar-compatible, allowing the secondary mirror to be removed and replaced with a third party lens accessory for ultra-fast f/2 wide field imaging.

CGX Mount

Several years ago Celestron engineers polled the larger dealers to see what features we would like to see in a German equatorial mount. The new CGX is the result of that effort and nearly three years of engineering effort. 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 aremechanical and ergonomic improvements to make the mount sturdier, easier to use, and transport. The CGX is a new Equatorial backbone to support a wide range of telescopes.
