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.
Technology
CGX Mount and Tripod Features
- Sturdier and more rigid with quicker dampening time
- Increased load capacity to 55 lbs.
- Motors provide more torque, better slewing and tracking under heavy loads
- Heavy Duty belt-drive system minimizes backlash while providing smooth motor operation under heavy loads
- Spring-loaded brass worm wheel and stainless steel worm gear reduce friction and provide optimum gear mesh
- 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
- 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 3°-65° latitude range
- Dual-fit CG-5/Vixen and CGE/Losmandy dovetail saddle
Tripod includes:
- 2" steel legs with height index marks for quick leveling
- "Jack of all trays" can hold three 1.25" eyepieces, two 2" eyepieces, your smartphone, or other accessories
- +20° of additional tracking past the meridian on either side
- Tripod legs can be collapsed with accessory tray installed for faster setup and transport
Ergonomics:
- Two handles for easy pickup and transport
- Ergonomically designed dovetail clamping knobs
- Innovative and improved polar alignment adjustment system
- Ergonomic latitude adjuster for smooth and easy adjustment under full loads
- Optional add-on polar axis finderscope

| Solar Warning |
- Never look directly at the Sun with the naked eye or with an optic (unless you have the proper solar filter). Permanent and irreversible eye damage may result.
- Never use your optic to project an image of the Sun onto any surface. Internal heat build-up can damage the optic and any accessories attached to it.
- Never leave your optic unsupervised. Make sure an adult who is familiar with the correct operating procedures is with your optic at all times, especially when children are present.
