Summary




TheCelestron CGEM 800 Computerized Telescope features a high-end 8" Schmidt Cassegrain OTA with the famous XLT coatings mounted on our brand new CGEM™ mount.

Ergonomic CGEM MountDesign
The CGEM™ mount is not just a pretty face with its new and bold appearance. It is fully capable of carrying Celestron’s higher-end SCT optical tubes securely and vibration free. This makes it perfect for both imaging and visual observing purposes. 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.

Ingenius Innovation
The CGEM series aim to make things easier with the All-Star Polar Alignment procedure which allows you to choose any bright star in the sky, while the software calculates and assists with polar alignment. Another reason why the CGEM is great for astrophotography is the Permanent Periodic Error Correction (PPEC).This feature is meant to train out the worm gears periodic errors, while allowing for the mount to maintain the PPEC recordings.

Great Performance
For objects near the Meridian (which is 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.

Celestron CGEM 800 Computerized Telescope Features:
- CGEM Computerized Equatorial Mount
- Ultra sturdy 2" steel tripod with Accessory Tray
- 40,000 object database with 400 user-definable objects and expanded information on over 200 objects
- NexStar computer control technology
- 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
- Permanent programmable periodic error correction (PPEC)
- Steel worm gear and 90mm pitch diameter brass worm wheel
- Drive Motors - Low Cog DC Servo motor with motor armatures thatare skewed to minimize cogging which is required fro low speed tracking.
- Designated six-pin RJ-12 modular jack, ST-4 compatible guide port
- Double line, 16-character Liquid Crystal Display Hand Control with backlit LED buttons for easy operation of goto features
- Autoguide port and auxiliary ports located on the electronic pier for long exposure astrophotography
- RS-232 communication port on hand control
- Includes NexRemote telescope control software
- GPS-compatible with optional CN16 GPS Accessory
