Telescopes Optics Type of build EdgeHD-Cassegrain

Celestron’s aplanatic EdgeHD optics revolutionized astroimaging.

EdgeHD Optics

EdgeHD is an aplanatic flat-field Schmidt optical system designed to produce aberration-free images with pinpoint stars all the way to the edge of the field of view of today’s largest imaging sensors and wide field eyepieces.

EdgeHD virtually eliminates both field curvature and off-axis star coma, providing an astrograph-quality system at a fraction of the price of competitors.
