Celestron CGEM 1100 Computerized Telescope: £2895.00

Offers portability and precision with high quality optics

Celestron's CGEM-1100 features our high-end 11" Schmidt Cassegrian OTA with XLT coatings mounted on our brand new CGEM™ mount.

The CGEM™ mount has a fresh, attractive, bold appearance and is capable of carrying Celestron’s higher-end SCT optical tubes (up to 11") securely and vibration free which is ideal for both imaging and visual observing.

Ergonomic Design - CGEM 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.

Innovation - 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.

Performance - 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 user defined programmable objects and enhanced information on over 200 objects.

Celestron's CGEM mount is the perfect fit between the Advanced Series and CGE Series. Offering the portability of the Advanced Series and the precision of the CGE.

General Details:

11" Schmidt-Cassegrain telescope
CGEM Computerized Equatorial Mount
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
Celestron's premium StarBright XLT coatings
9x50 finderscope to help accurately find objects
Ultra sturdy 2" steel tripod with Accessory Tray
Star diagonal provides more comfortable viewing position when observing objects that are high in the sky
40,000 object database with 400 user-definable objects and expanded information on over 200 objects
Proven NexStar computer control technology
New "All-star" Polar alignment uses any bright star for a quick and accurate Polar alignment
Software Features include: Mount Calibration, Database Filter Limits, Hibernate, five Alignment Procedures
Flash upgradeable hand control software and motor control units for downloading product updates over the Internet
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 star; solar systems; objects and asterisms
Permanent programmable periodic error correction (PEC) - corrects for periodic tracking errors inherent to all worm drives
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.
Internal Cable wiring for trouble-free setup and transportation
Designated six-pin RJ-12 modular jack, ST-4 compatible guide port
Autoguide port and auxiliary ports located on the electronic pier for long exposure astrophotography
Double-line, 16-character Liquid Crystal Display Hand Control with backlit LED buttons for easy operation of goto features
RS-232 communication port on hand to control the telescope via a personal computer
Includes NexRemote telescope control software, for advanced control of your telescope via computer
GPS compatible with optional CN16 GPS Accessory
