CELESTRON  •  CGEM-800  8" SCT on CGEM Equatorial Mount  •  11097

The Celestron CGEM-800 telescope package is a full-featured scope with computerized "GO-TO" observing capabilities as well as  "straight-out-of-the-box" professional imaging quality. Use it simply to observe, and its NexStar controller makes viewing un-complicated, even for a beginner. Its heavy-duty CGEM equatorial mount will provide a rock-solid base for imagery, free from annoying jitters which can frustrate even the best of optics, plus it also learns over time to correct for the periodic tracking errors (PEC) inherent in every telescope mount. The combination of aperture, automation, and price will appeal to anyone with a dual interest in both viewing and astrophotography.


General Features:

  • 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
  • Star diagonal provides more comfortable viewing position when observing objects that are high in the sky
  • Ultra Sturdy 2" steel tripod with Accessory Tray
  • 8" Schmidt-Cassegrain telescope
  • Celestron's premium StarBright XLT coatings
  • 6x30 finderscope to help accurately find objects

 

Computerized Mount Features:


  • 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.
  • Includes NexRemote telescope control software, for advanced control of your telescope via computer
  • New "All-star" Polar alignment uses any bright star for a quick and accurate Polar alignment
  • 40,000 object database with 400 user-definable objects and expanded information on over 200 objects
  • Permanent programmable periodic error correction (PEC) - corrects for periodic tracking errors inherent to all worm drives
  • Proven NexStar computer control technology
  • Double line, 16-character Liquid Crystal Display Hand Control with backlit LED buttons for easy operation of goto features
  • 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

  • Internal Cable wiring for trouble-free setup and transportation
  • Flash upgradeable hand control software and motor control units for downloading product updates over the Internet
  • Software Features include: Mount Calibration, Database Filter Limits, Hibernate, five Alignment Procedures, and user-defined slew limits
  • Steel worm gear and 90mm pitch diameter brass worm wheel
  • RS-232 communication port on hand control to control the telescope via a personal computer
  • Autoguide port and auxiliary ports located on the electronic pier for long exposure astrophotography
