| 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 TECHICAL SPECIFICATIONS: OPTICAL DESIGN: 9.25" Schmidt-Cassegrain FOCAL RATIO: 10 FOCAL LENGTH: 2350 mm (92.52 in) APERTURE: 235 mm (9.25 in) FINDERSCOPE: 6x30 MOUNT: Computerized Equatorial OPTICAL COATINGS: Starbright XLT Coatings OPTICAL TUBE: Aluminum EYEPIECE 1: 25 mm (0.98 in) MAGNIFICATION 1: 94 x STAR DIAGONAL: 1.25 TRIPOD: Adjustable, Stainless Steel CD ROM: NexRemote control software with RS232 cable POWER SUPPLY: Car battery adapter HIGHEST USEFUL MAGNIFICATION: 555 x LOWEST USEFUL MAGNIFICATION: 33.57 x LIMITING STELLAR MAGNITUDE: 14.4 RESOLUTION (RAYLEIGH): 0.59 arcsec RESOLUTION (DAWES): 0.49 arcsec EYEPIECE 1 FIELD OF VIEW: .53 ° LIGHT GATHERING POWER: 1127 x ANGULAR FIELD OF VIEW: 0.53 ° SECONDARY MIRROR OBSTRUCTION: 3.35 in (85.09 mm) SECONDARY MIRROR OBSTRUCTION BY AREA: 13.1 % SECONDARY MIRROR OBSTRUCTION BY DIAMETER: 36.2 % GEAR: Steel worm gear and 90mm pitch diameter brass worm wheel MOTOR DRIVE: Low cog DC Servo motors with encoders, both axes COMPUTER HAND CONTROL: Double line, 16 character Liquid Crystal Display; 19 fiber optic backlit LED buttons SLEW SPEEDS: Nine slew speeds: 5°/sec, 2°/sec, 1°/sec, 64x, 16x, 8x, 4x, 1x, .5x TRACKING RATES: Sidereal, Solar and Lunar TRACKING MODES: EQ North and EQ South ALIGNMENT PROCEDURES: 2-Star Align, Quick Align, 1-Star Align, Last Alignment, Solar System Align SOFTWARE PRECISION: 24bit, 0.08 calculation DATABASE: 40,000+ objects, 400 user defined programmable objects.
