New Celestron CGX 8" EdgeHD Telescope

The CGX 925 HD combines Celestron's all-new state of the art CGX computerised equatorial mount with its acclaimed EdgeHD optical system.  With over 9 inches of aperture and premium StarBright XLT coatings, the CGX 925 HD gives you over 1000 times the light gathering power than the unaided eye.  Delivers more resolution than the 800 with less weight than the 1100, the CGX 925 HD is well suited for remote operation.

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.

For eight years, 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 Celestron’s technologies, value, and ease-of-use.

The new CGX was designed to support your telescope for both visual and astro-imaging pursuits.  Key design goals included a lower profile EQ head for 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, there are several mechanical and ergonomic improvements to make the mount sturdier, easier to use and transport.
