Celestron put together this CGX Equatorial 1100 Rowe-Ackermann Schmidt Astrograph Telescope kit with the combination of their fast focal ratio astrograph and their updated CGX motorized and computer-controlled GoTo mount.

11" f/2.2 Rowe-Ackermann Schmidt Astrograph Telescope (OTA only)

The 11" f/2.2 Rowe-Ackermann Schmidt Astrograph Telescope from Celestron is specifically designed for astrophotography and astroimaging with a large 11" aperture and fast f/2.2 focal ratio. The OTA is being offered by itself without a mount, and comes with a Celestron CGEM-style dovetail plate for use on compatible mounts and tripods. Using 4-element rare-earth optical glass lenses ensures accurate color rendition and elimnates aberrations such as coma and field curvatures. The improved StarBright XLT multi-coating system, which includes anti-reflection coatings on the lenses and highly-reflective coatings on the mirrors, increases light transmission throughout the entire optical path. A 12V MagLev fan reduces cooldown time and provides optimal airflow through the optical tube while filtering harmful dust from the interior.

The 43.3mm imaging circle is made to cover today's large DSLR and CCD imaging sensors to capture full-frame shots with vignetting, while a fast focal ratio reduces exposure times without sacrificing image quality and gives the user more time for multiple shots of the same object for layering or with different filters. A custom-designed FeatherTouch micro focus system has a 10:1 reducer with linear brass focuser bearing to enables very precise focusing to clearly resolve topographic details on the Moon or split double stars, and reveal details of most other celestial objects in between. Since this OTA is designed as an imaging scope, a 42mm T-thread camera adapter and 48mm camera adapter are provided. Other adapters are available if required.


Celestron 11" RASA Astrograph OTA Highlights

  • The 11" f/2.2 Celestron RASA unique Rowe-Ackermann optical design built with rare-earth glass for images free of false color, coma, and field curvature
  • This beautiful astrograph yields a 43.3 mm image circle when used with included camera adapters that maintains pinpoint stars to the far corners of even the largest astro-imaging sensors
  • The Celestron RASA includes a dual speed 10:1 Feather Touch Micro Focus Knob and custom-engineered linear brass bearings for precision focusing with minimal image shift.
  • A quiet, high-output 12V MagLev fan reduces cool down time and blocks dust.
  • The Celestron Rowe-Ackermann Schmidt Astrograph includes common camera adapters (T-thread and M48) for easy attachment to popular CCD and DSLR cameras

Celestron CGX Equatorial Mount Highlights

  • The CGX Mount has a large 55 pound weight capacity!
  • More responsive, the CGX mount has spring-loaded worm gears with belt drives to minimize backlash.
  • Easily mount a wide range of optical tube assemblies on the CGX dual-fit CG-5 (Vixen)/CGEM (Losmandy) dovetail saddle plate.
  • Internal cabling, Home and Limit switches, internal hard stops for both axes work to prevent cable wrap, tripod strike, and keep your cables safe and out of the way.
  • The CGX tracks 20-degrees past the meridian on either side, supporting you in your astro-imaging endeavors.
  • All-Star Polar Alignment technology is built-in, making polar alignment easier and faster. The CGX mount also supports StarSense AutoAlign.
  • Improved ergonomics and intuitive carry-handles
  • Sophisticated telescope control software is all new and designed in conjunction with Planewave Instruments. Features include multi-point GoTo modeling, focusing and plate solving.
  • No third party advanced PC control software is necessary.
  • Mount weighs just 44 pounds, making it very portable.
  • Included heavy-duty tripod has 2" stainless steel legs with graduated marks to make leveling easier.
