  • Internal cabling for worry-free remote operation. Power input and accessory ports remain stationary while the mount slews to avoid snags
  • Internal hard stops for both axes prevents cable tension and tripod strike
  • Internal optical sensors on both axes for simple and safe remote operation
  • Home sensors allow the mount to always start in the index position regardless of orientation before a power reset
  • Limit sensors automatically shut off slewing or tracking before reaching the hard stop fail safe
  • Brand new control software developed in conjunction with PlaneWave Instruments for professional level control operation and imaging
  • Software includes multi-point mount modeling for extremely precise pointing accuracy and many more additional features for remote astroimaging
  • Wider tripod stance for improved stability
  • Adjustable EQ head position to optimize center of gravity over the tripod and fully utilize the increased 3º-65º latitude range
  • Dual-fit CG-5/Vixen and CGE/Losmandy dovetail saddle

Description

The CGX 1100 Schmidt-Cassegrain Telescope features Celestron’s premium StarBright XLT coated optics and the all-new state of the art CGX computerized equatorial mount. With the optical tube assembly of the CGX 1100 weighing only 27.5 lb., this telescope is still portable enough to be taken to dark skies, and it has 89% more light gathering power than an 8" telescope and more than 40% more than the 9.25".

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 all-new CGX EQ, a culmination of all the advancements made to our technologies, value, and ease-of-use.

The new 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 new Equatorial backbone to support a wide range of telescopes.
