Celestron EdgeHD 8" Optical Tube AssemblyThe EdgeHD is an aplanatic, flat field Schmidt-Cassegrain telescope that produces 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; it also provides an astrograph-quality flat focal plane all the way to the edge of the field of view.The Celestron EdgeHD Telescope advantages: wide and fully corrected field for astro photography - flat and free of coma. unrestricted visual suitability
Main mirror lock - prevents the mirror from shifting Main mirror ventilation for shorter cool-down time Every HD telescope is Fastar compatible and can be turned into a f/2 Schmidt Camera. With the StarBright XLT, Celestron disposes of one of the best coatings we know. Thus offering the HD telescopes a very bright and full-contrast picture. Easy Collimation: guarantees ideal performance every time. Edge HD?s precision-machined mechanics and a spherical secondary mirror make collimation simple and accurate.
