Product Description

CELESTRON - CGEM 925 Equatorial HD Computerized 9.25" Telescope • 11081

The Celestron CGEM Equatorial Mount is designed for both visual astronomy and astro-imaging. Since it has a 40 Ib payload, it is designed to hold Celestron's larger   optical tube assemblies such as the 9.25" EdgeHD. Adding Celestron's own StarBright XLT coatings, this telescope will provide a light gathering 1000x more than the unaided eye can detect. For visual astronomy, the Celestron EdgeHD system provides pinpoint stars over the entire field of view even when using a wide field eyepiece. It is also a major advantage for astro-imaging due to its ability to virtually eliminate coma seen in regular Schmidt-Cassegrain designs, and overall provide an aberration free image even when using some of the largest CCD chips in the marketplace. Since most Schmidt-Cassegrain optical tubes have a curved focal plane, this can render out of focus stars at the edge of a field of view when using a flat sensor. The EdgeHD optics provide a focal plane three-times flatter so this isn't an issue. Higher resolution is also a plus here because more detail can also be detected throughout the entire field of view. For instance, one might be able to detect apparent double stars at the edge of the field of view.


  • 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


 CGEM Equatorial Mount

  • Proven NexStar computer control technology
  • 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
  • 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 plate 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 SkySync GPS Accessory
  • Precision machined 40 mm diameter steel Polar shafts supported by multiple tapered roller bearings and ball bearings.
  • Secure power plug ensures that the mount's power source is not accidentally disconnected
