Celestron 11" Schmidt-Cassegrain CGX Telescope



The Celestron CGX 1100 Schmidt Cassegrain Telescope and Mount features the high-end 279 mm (11-inch) Schmidt-Cassegrain OTA with StarBright XLT coatings mounted on the brand new CGX mount. The CGE PRO style 2.75-inch leg tripod holds 14-inch optics securely while dampening vibration, which is ideal for both imaging and visual observing.

With sophisticated software features like the Hibernate function, the CGX can maintain its star alignment night after night without needing to be realigned!

Experience the improved Performance of the Celestron CGX Schmidt Cassegrain Telescope and Mount

Innovative Design - The Celestron CGX mount is incredibly ergonomic, with the convenient carrying handles and easy to use turn knobs. The Celestron CGX series provides internal cabling that bypasses the issue of cable twisting or tangling. Route all your power supply and accessory cables into a convenient port on a part of the mount that moves. The cables enter into the mount, contained, and reach everywhere they need to without any tangling issues.

Revamped Engineering - This mount boasts drastically reduced backlash and improved stability. Also incredibly rigid, this mount has an improved motor system that greatly boosts the provided torque.

Peak Optics - For objects near the Meridian (imaginary line passing from North to South), the Celestron CGX mount will track a full 20 degrees past the Meridian for uninterrupted imaging through the most ideal part of the sky. The CGX mount has a robust database with over 40,000 objects, utilizing a top-quality NexStar hand controller.

Included Technology

All-Star Polar Alignment

Get ready for a night of astroimaging with your mount faster than previously thought possible with All-Star Polar Alignment. This innovative software solves the time-consuming problem of trying to pinpoint the North Celestial Pole.

Compatible Technology


The new Lithium Phosphate (LiFePO4) battery chemistry has significant advantages over other battery chemistries, great for those Astronomers on the go.

Starsense Technology

Celestron’s patented StarSense Technology makes it easier than ever to locate objects in the night sky, even if you’ve never used a telescope before. Turn it on and push ‘Align.’ In about three minutes, you’re ready to observe!


WiFi technology encircles the globe in a web of connectivity, knowledge, and information. Now, Celestron is using that same technology to allow stargazers to connect to the night sky and enhance their experience of the cosmos in fun and unique ways.
