About this product
Model: cel_cgx_1100_edgehd_12057
Part Number: 12057-CGL
The CGX 1100 HD combines Celestron's all-new state of the art CGX computerised equatorial mount with its acclaimed EdgeHD optical system.
With an optical tube assembly weighing only 12.7 Kg (28 lbs) this telescope is still portable enough to be taken to dark skies, and it’s 11” aperture delivers 89% more light gathering power than an 8" telescope and 40% more than the 9.25".
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.
