Celestron SCT Telescope 8" SCT w/ CGEM-800 Mount 11097

Item No. 102-11097
Manuf. No. Celestron 11097

Celestron's CGEM-800 telescope offers stable performance and convenient portability for amateur astronomers. Featuring an 8" Optical Tube with StarBright XLT coatings it is the most portable model within the CGEM telescope series weighing only 88 lbs., and its ergonomically designed mount provides stargazers the ease of use and mobility they need.

As a visual instrument you can search for all of the Messier Catalog objects, and you can see hundreds of other equally interesting NGC, IC and Caldwell objects. Turn this scope to the planets and see amazing detail on the surface of Jupiter; see Cassini's Division in the rings of Saturn, and resolve details on the surface of Mars. Even the distant Uranus, Neptune and Pluto are within your reach.

The CGEM-800 Equatorial mount also offers numerous design advantages:

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 (patent pending). 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, 400 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.

FEATURES

  • 8" Schmidt-Cassegrain telescope
  • 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
  • Celestron's premium StarBright XLT coatings
  • 6x30 finderscope to help accurately find objects
  • Ultra Sturdy 2" steel tripod with Accessory Tray
  • Star diagonal provides more comfortable viewing position when observing objects that are high in the sky
  • 40,000 object database with 400 user-definable objects and expanded information on over 200 objects
  • Proven NexStar computer control technology
  • 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
  • Flash upgradeable hand control software and motor control units for downloading product updates over the Internet
  • 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
  • Permanent programmable periodic error correction (PEC) - corrects for periodic tracking errors inherent to all worm drives
  • Steel worm gear and 90mm pitch diameter brass worm wheel
  • 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.
