Celestron put together the CGX-L Equatorial 1100 11" f/10 Schmidt-Cassegrain GoTo Telescope to provide a complete observational platform that includes an over-sized-aperture optical tube assembly (OTA), the NexStar+ computer hand controller, an updated motorized equatorial mount and tripod, plus an array of accessories to get you set up and observing the Moon, planets, and especially deep-sky subjects like nebulae, galaxies, and star clusters.
Outfitted with an over-sized aperture, long effective focal length, and their proprietary StarBright XLT optical coatings, the Celestron C11-A XLT 11" f/10 Schmidt-Cassegrain Telescope provides power and portability. The coating system consists of anti-reflection coatings on the corrector plate, highly reflective index mirror coatings, and low-absorption/high-transmission glass components to ensure that the maximum amount of light is gathered and transmitted to the user's eye. This system ensures bright and clear high-contrast images with accurate color rendition across the entire visual spectrum without visible distortion at the edges. Celestron includes a standard 1.25" visual back to accept eyepieces and accessories such as the 40mm eyepiece and 90° diagonal supplied with the optical tube assembly (OTA). This OTA is offered here without a mount or tripod for users who already have a support system�just ensure the mount's payload capacity exceeds 27.5 pounds to safely carry the weight and that the mount has a Losmandy-style saddle to match the OTA's CGE mounting plate.

- High-transmission water white glass corrector plate limits light loss due to internal absorption
- Optical tube only�mount and tripod required for proper use
- Supplied with CGE dovetail plate, which is compatible with Losmandy-style saddles
- Mount must have a payload capacity of over 27.5 pounds to safely support the OTA

- Mounting bracket included
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.
