General Features

  • 9.25" EdgeHD Optics
  • Celestron premium StarBright XLT coatings
  • CGE PRO computerized Equatorial mount
  • 9x50 finderscope with quick release bracket to help accurately find objects
  • 2" Star diagonal provides more comfortable viewing position when observing objects that are high in the sky
  • Heavy Duty stainless steel tripod adjustable from 38 - 55"

HD Features

  • New aplanatic Schmidt telescope design produces aberration-free images across a wide field of view
  • Focus adjustment is supported by two pre-loaded ball bearings to minimize the "mirror flop" typical of bushing focus mechanisms
  • Flexible tension mirror locks hold the mirror in place and reduces image shift
  • Cooling vents located on the rear cell allows warm air to be released from behind the primary mirror
  • Fastar ready optics for ultra wide f/2 imaging

Computerized Mount Features

  • Proven NexStar computer control technology
  • 40,000 object database with over 100 user-definable objects and expanded information on over 200 objects
  • New All-Star Polar Alignment routine for both Northern and Southern Hemispheres
  • Software Features include: Database Filter Limits, Hibernate, five alignment methods and user-defined slew limits
  • Custom Rate 9 feature allows you set maximum slew rate
  • Tandem mode allows you to star align the mount even when positioned for tandem scope use
  • 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 stars; solar system objects and asterisms
  • Double line, 16-character Liquid Crystal Display Hand Control with backlit LED buttons for easy operation of Go-To features
  • 12 VDC Servo Motors with integrated optical encoders
  • Permanent Programmable Periodic Error Correction (PEC) - corrects for periodic tracking errors inherent to all worm drives
  • Drive Motors - High quality motors with seven slot skewed armature to minimize magnetic cogging for quiet operation and long life. Precision made cut-steel gears in gearbox for improved tracking precision
  • Bearing and Shaft - Main shafts are made from 1.57" diameter steel tubing with .40" wall thickness with two preloaded 2.68" O.D. tapered roller bearings on each axes
  • Precision worm drive system - .75" pitch dia. precision made steel worm preloaded with two .87" OD ball bearings to minimize run-out (a source of periodic error). 255 tooth 6" pitch dia. precision made worm wheel with enveloping brass teeth
  • Spring loaded DEC worm to minimize backlash and makes guiding easy
  • 4 point RA and DEC clutch system for no-slip pointing precision
  • Autoguide port, PC port and Auxiliary ports located on the electronic pier for long exposure astrophotography
