Celestron CGEM 925 HD Computerized Telescope

TRUE ASTROGRAPH QUALITY

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

IMPROVED PERFORMANCE

Superior edge performance not only creats rounder, more pleasing stars but actually improves the resolution and limiting magnitude when compared to telescopes of equal aperature.

STARBRIGHT XLT COATINGS

Coupled with Celestron's StarBright XLT coating group on every surface, EdgeHD optics gives you maximum light throughout across the widest visual and photographic spectrum.

EdgeHD is an aplanatic Schmidt telescope designed to produce aberration-free images across a wide visual and photographic field of view. The optical system was designed to reduce more than just off-axis star coma, but also to give an astrograph quality flat focal plane all the way to the edge of the field of view.

Features:

  • EdgeHD Optics
  • Celestron premium StarBright XLT coatings
  • Mirror Clutches - Flexible tension clutches hold the mirrot in place and reduce image shift when ratating the tube around the mount
  • All EdgeHD optical tubes are Fastar comptiable for ultra fast f/2 wide field imaging
  • Tube Vents - Cooling vents located on the rear call allow hot air to be released from behind the primary mirror
  • 9X50 finderscope with quick release bracket to help accurately find objects
  • Star diagonal provides a more comfortable viewing position when observing objects that are high in the sky
