Celestron CGX-L Equatorial 1100 11" f/10 Schmidt-Cassegrain GoTo Telescope

Celestron CGX-L 1100 Overview

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.

Celestron C11-A XLT 11" f/10 Schmidt-Cassegrain Telescope (OTA Only, CGE Dovetail)

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.

Optical Tube

  • 11" (279.4mm) aperture
  • f/10 focal ratio
  • 2800mm effective focal length
  • Schmidt-Cassegrain design optical path
  • StarBright XLT optical coatings
  • Resolution: 0.5 arcsec (Rayleigh); 0.42 arcsec (Dawes)
  • Secondary mirror obstruction: 3.75" (95 mm); 34% by diameter; 12% by area

StarBright XLT System

  • Maximizes light transmission through optical path
  • Improves color rendition, contrast, sharpness, resolution, and brightness

  • Multi-layer mirror coatings with layers of aluminum, SiO2 (quartz), and TiO2 (titanium dioxide)
  • Multi-layer anti-reflective corrector plate coatings with layers of MgF2 (magnesium fluoride) and HfO2 (hafnium dioxide); hafnium has a wider band-pass than the commonly used titanium
  • High-transmission water white glass corrector plate limits light loss due to internal absorption

Mounting

Celestron CGX-L GoTo EQ Mount with Tripod

With an upgraded payload capacity, tripod, and internal gears, the Celestron CGX-L GoTo EQ Mount improves on their 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 75 lb 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 Vixen/Losmandy dual dovetail saddle has also been lengthened to 10.6" to improve stability and offer greater security for larger OTAs. To provide a solid platform for the mount and your OTA, a heavy-duty stainless steel tripod is included, sporting massive 2.75"-diameter legs, an accessory tray that doubles as a stabilizer, and an adjustment range from 35.75" to 52.75". The minimum height has been lowered almost a foot versus the earlier CGX model to accommodate a wider range of users and different observation positions.

The brain of the CGX-L is the venerable 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 200 custom user-defined objects with filters added for 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.
