Celestron CGE Pro 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.
