Product Details

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. Capable of holding over 40 lbs of payload and slewing at 5° per second, you will be able to instantly point to any of the celestial objects in the database.

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™. 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, 100 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 Features

Computerized Mount Features

  • 40,000 object database with over 100 user-definable objects and expanded information on over 200 objects
  • Proven NexStar computer control technology
  • Redesigned electronics deliver constant regulated power to the motors making them capable of driving the telescope even when not perfectly balanced
  • Flash upgradeable hand control software and motor control units for downloading product updates over the Internet
  • 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, and user-defined slew limits
  • Meridian preference for slewing - allows you to approach an object from the side of the Meridian that maximizes tracking (and imaging) time
  • 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
  • Solar System alignment method - allows you to align your telescope and view the moon and planets during the day
  • Permanent Programmable Periodic Error Correction (PEC) - corrects for periodic tracking errors inherent to all worm drives
