The Celestron CGX-L GoTo EQ Telescope Mount Head improves on the venerable CGX platform to provide users with a heavy-duty research-quality mount for larger optical tube assemblies (OTAs), accessories, and imaging rigs.

Engineered to carry a heavy 75-pound payload, and outfitted with high-torque motors and a heavy-duty belt-drive system to improve tracking stability and reduce backlash, it is able to smoothly and accurately track near- and deep-sky objects for extended periods of time.

The brain of the CGX-L is the NexStar+ computer controller. Equipped with a database of 40,000 objects, including the planets, stars, nebulae, galaxies, and the complete Messier catalog, it can also be programmed with up to 200 custom user-defined objects with filters added to custom object lists. Its intuitive menu-driven user interface gives you the power to observe the heavens with nine slew speeds, three tracking rates, anti-backlash compensation, and Permanent Periodic Error Correction (PPEC) for smoother movements in the motors and improved tracking over time. Features such as guided tours, extended information on 200 popular objects, and multiple alignment options make the NexStar+ controller easy to use and invaluable to both new users and experienced stargazers.

Celestron offers this version of the CGX-L mount without a tripod for users who already have a tripod or pier. The Vixen/Losmandy dual dovetail saddle has also been lengthened to 10.6" to improve stability and offer greater security for larger OTAs.
