Celestron CGX 800 EdgeHD Corrected Schmidt-Cassegrain Telescope is an aplanatic 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.
EdgeHD optics produce a focal plane more than three-times flatter than a standard Schmidt-Cassegrain telescope and dramatically flatter than other competing coma-free designs. This guarantees you visibly sharp stars across some of the largest CCD chips available today.
Features of the Celestron CGX 800 EdgeHD
Ergonomic Design - The Celestron CGX mount is incredibly ergonomic, from the convenient carrying handles to the easy to use and turn knobs.
Splendid Engineering-This mount boasts drastically reduced backlash and improved stability. Incredibly rigid, this mount also boasts an improved motor system that greatly boosts the provided torque. It's simply superior to its predecessors in every way.
Innovation - The Celestron CGX series boasts internal cabling that utterly bypasses the issue of cable twisting or tangling by letting you route all your own power supply and accessory cables into a convenient port on a part of the mount that moves- from which they enter into the mount, utterly contained, and reach everywhere they need to on the inside without any tangling issues. Neat and clean!
Performance - For objects near the Meridian (imaginary line passing from North to South), the Celestron CGX mount will track a full 20 degrees past the Meridian for uninterrupted imaging through the most ideal part of the sky. The CGX mount has a robust database with over 40,000 objects, utilizing a top-quality Nexstar hand controller.
Superior mount performance combined with superior edge performance not only creates rounder, more pleasing stars but actually improves the resolution and limiting magnitude when compared to telescopes of equal aperture. When it comes to the Celestron HD series coupled with Celestron's StarBright XLT coating group on every surface, EdgeHD optics gives you maximum light throughput across the widest visual and photographic spectrum. It's a vision you'll never forget.
