  • CGEM Computerized Equatorial Mount
  • Celestron's premium StarBright XLT coatings
  • 9x50 finderscope to help accurately find objects
  • Ultra sturdy 2" steel tripod with Accessory Tray

HD Features:

  • New aplanatic Schmidt telescope design produces aberration-free images across a wide field of view
  • Mirror tension locks hold the primary mirror in place and reduces image shift
  • Cooling vents allow hot air to be released from behind the primary mirror
  • Fastar compatible for fast f/2 imaging

The CGEM was designed to be ergonomically friendly with large altitude and azimuth adjustment knobs for quick and easy polar alignment adjustment. CGEM has an innovative polar alignment procedure called All-Star. All-Star allows users to choose any bright star from the hand control, while the software calculates and assists with polar alignment.

Computerized Mount Features:

  • 40,000 object database with over 100 user-definable objects and expanded information on over 200 objects
  • Redesigned electronics deliver constant regulated power to the motors making them capable of driving the telescope even when not perfectly balanced.
  • 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
  • Meridian preference for slewing - allows you to approach an object from the side of the Meridian that maximizes tracking (and imaging) time.
  • Solar System alignment method - allows you to align your telescope and view the moon and planets during the day
  • Custom Rate 9 feature allows you set maximum slew rate
  • Tandem mode allows you to star align the mount even when positioned for tandem scope use.
  • 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
  • Permanent Programmable Periodic Error Correction (PEC) - corrects for periodic tracking errors inherent to all worm drives

  • 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 plate for long exposure astrophotography
  • Double-line, 16-character Liquid Crystal Display Hand Control with backlit LED buttons for easy operation of go to features
