Celestron Advanced VX 9.25" EdgeHD Computer GoTo Telescope

The Celestron CGEM II 925HD telescope puts unique new 9.25" aperture aplanatic (free from coma andcorrected for spherical aberration) EdgeHD high definition/high contrast Schmidt optics on a precision Celestron CGEM II go-to German equatorial mount. The advanced EdgeHD optical design -Sky & Telescope Hot Product for 2010- has a dual-element field flattener lens made from premium Schott optical glass in its central baffle tube that reduces off-axis coma and produces aberration-free images across a wide 42mm image circle (as large as the diagonal of a 35mm negative or large format CCD chip and ideal for astrophotography). And those images will look superb through the supplied ultra-premium 82 deg; field 23mm 2" Celestron Axiom eyepiece.

In addition to reduced off-axis coma, the EdgeHD optical system delivers an astrograph-quality focal plane more than three times flatter than a standard Schmidt-Cassegrain telescope and dramatically flatter than competing coma-free designs. Stars are smaller and more concentrated, creating brighter images and allowing you to see down to a fainter magnitude than other equally-sized telescopes. You see visibly sharp and point-like stars to the very edges of some of the largest CCD and DSLR chips available today.
