Celestron CGEM DX 1100 HD 11" EdgeHD Schmidt-Cassegrain Telescope 2800mm Focal Length -

Celestron's CGEM-1100 telescope offers premium performance and mobility for stargazers seeking the ultimate Astronomy experience. It features an 11" Optical Tube weighing only 27.5 lbs. and a telescope mount with a unique ergonomic design for ease of use and convenient mobility. Equipped with StarBright XLT coatings it can capture up to 89% more light gathering power than an 8" telescope. The CGEM-800 Equatorial mount was designed to be ergonomically friendly with large Altitude and Azimuth adjustment knobs for quick and easy polar alignment adjustment.
The internal RA and DEC motor wiring provides a clean look and an easy and trouble free set up. The CGEM series has a new innovative Polar alignment procedure called All-Star (patent pending). All-Star allows users to choose any bright star, while the software calculates and assists with polar alignment. Another great feature of the CGEM, sure to please astroimagers, is the Permanent Periodic Error Correction (PEC) which will allow users to train out the worm gears periodic errors, while the mount retains the PEC recordings.
For objects near the Meridian (imaginary line passing from North to South), the CGEM will track well past the Meridian for uninterrupted imaging through the most ideal part of the sky. The CGEM mount has a robust database with over 40,000 objects, 400 users' defined programmable objects and enhanced information on over 200 objects.

Lining and Layers:

  • Double-line, 16-character Liquid Crystal Display Hand Control with backlit LED buttons for easy operation of goto features

Support and Cushioning:

  • Precision machined 40 mm diameter steel Polar shafts supported by multiple tapered roller bearings and ball bearings
  • Schmidt-Cassegrain mechanism that moves the primary mirror to adjust focus is supported by two pre-loaded ball bearings, minimizing the "mirror flop" typical of bushing focus mechanisms


  • Star diagonal provides more comfortable viewing position when observing objects that are high in the sky


  • Designated six-pin RJ-12 modular jack, ST-4 compatible guide port
  • New "All-star" Polar alignment uses any bright star for a quick and accurate Polar alignment
  • RS-232 communication port on hand to control the telescope via a personal computer
  • Custom database lists of all the most famous deep-sky objects by name and catalog number: the most beautiful double, triple and quadruple stars; variable stars; solar system objects and asterisms
  • Internal Cable wiring for trouble-free setup and transportation
  • 40,000 object database with over 100 user-definable objects and expanded information on over 200 objects
  • Drive Motors - Low Cog DC Servo motor with integrated optical encoders offer smooth, quiet operation and long life. The motor armatures are skewed to minimize cogging which is required for low speed tracking
  • Ultra sturdy 2.75 inch steel tripod with Accessory Tray
  • Secure power plug ensures that the mount's power source is not accidentally disconnected
  • Celestron's premium StarBright XLT coatings
  • 9x50 finderscope to help accurately find objects
  • GPS compatible with optional SkySync GPS Accessory
  • Proven NexStar computer control technology
  • Includes NexRemote telescope control software, for advanced control of your telescope via computer
  • Permanent Programmable Periodic Error Correction (PEC) - corrects for periodic tracking errors inherent to all worm drives
  • Flash upgradeable hand control software and motor control units for downloading product updates over the Internet
  • Autoguide port and Auxiliary ports located on the electronic plate for long exposure astrophotography
