  Description

  True Astrograph Quality
  Many optical designs that advertise themselves as astrographs actually only produce pinpoint stars across a curved focal plane. While this may be acceptable for some visual observing, stars will appear out of focus at the edge when used with the flat chip sensor of a digital camera. EdgeHD optics produce a focal plane more than three-times flatter than a standard Schmidt-Cassegrain telescope and dramatically flatter than competing coma-free designs. This guarantees you visibly sharp stars across some of the largest CCD chips available today.

  Individually Tested
  Every EdgeHD that ships has been tested not only for the surface quality of each optical component, but also with a camera and artificial star to ensure the imaging system meets our rigid quality assurance. This “final acceptance test” confirms the EdgeHD will perform in the field and deliver high-quality astroimages.

  MOUNT INFO

  A fresh update to the venerable CGEM mount, the CGEM II has a fresh, attractive, bold appearance and is capable of carrying Celestron’s higher-end SCT optical tubes (up to 11 ) securely and vibration free, which is ideal for both imaging and visual observing. Capable of holding 40 lbs. of payload and slewing at 5° per second, you will be able to instantly point to any of the celestial objects in the database.  

  FEATURES 

  • 40 lbs payload capacity
  • Dual-fit Vixen CG-5 and Losmandy CGE dovetail saddle
  • 2 steel legs with height index marks for quick leveling
  • USB 2.0 port on hand control for direct links to a PC via ASCOM supported software
  • 40,000 object database with over 100 user-definable objects and expanded information on over 200 objects
  • Internal cabling throughout for worry-free remote operation
  • Low cog DC Servo motor with integrated optical encoders offer smooth, quiet operation
  • Able to track past the meridian allowing seamless imaging
  • Permanent periodic error corrections allow users to train out the worm gears periodic errors once, while the mount retains the PEC recordings.
  • Software Features include: Mount Calibration, Database Filter Limits, Hibernate, five Alignment Procedures, and user-defined slew limits
  • Built-in polar alignment program to polar align on any star in the sky
  • Longer clutch levers to make tightening and loosening of clutches easier
  • Custom database lists of all the most famous deep-sky objects by name and catalog number
  • Solar System alignment method allows to view the moon and planets during the day
  • Custom Rate 9 feature allows to set maximum slew rate
  • Tandem mode allows to star align the mount even when positioned for tandem scope use
  • USB hand control to control the telescope via a personal computer
