CGEM - 925 Computerised Telescope
GENERAL DETAILS:

9.25" 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
Drive Motors - Low Cog DC Servo motor with integrated optical encodes 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 pier 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 control 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 CN16 GPS Accessory
