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 XLT coatings mounted on the brand new CGX mount. The CGX mount is the newest member of Celestron's fully computerized Equatorial mount series capable of carrying Celestron's high-end 11-inch and 14-inch optical tubes. The CGE PRO style, 2.75-inch leg tripod holds even our 14-inch optics securely while dampening vibration, which is ideal for both imaging and visual observing. Capable of holding 55-pounds of payload and slewing at 5 degrees per second, you will be able to instantly point to any of the celestial objects in the database.

German Equatorial mounts are recognized for their rock solid stability, simple balancing and easy accessibility for attaching accessories. With sophisticated software features like the Hibernate function, the CGX can maintain its star alignment night after night without needing to be re-aligned, making it an excellent choice for a permanent observatory facility.

The Celestron CGX Mount is an innovative new design that improves on its predecessors in every imaginable way. It's the product of over three years of innovative design and planning, and it shows. 

Ergonomic Design - The Celestron CGX mount is incredibly ergonomic, with the convenient carrying handles and easy to use turn knobs.

Splendid Engineering - This mount boasts drastically reduced backlash and improved stability. Incredibly rigid, this mount also boasts an improved motor system that greatly boosts the provided torque. It's simply superior to its predecessors in every way.

Innovation - The Celestron CGX series boasts internal cabling that utterly bypasses the issue of cable twisting or tangling by letting you route all your own power supply and accessory cables into a convenient port on a part of the mount that moves- from which they enter into the mount, utterly contained, and reach everywhere they need to on the inside without any tangling issues. Neat and clean!

Performance - 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.
