This guarantees you visibly sharp stars across some of the largest CCD chips available today. 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. 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. Agena AstroProducts - Shop for Quality Telescopes, Eyepieces, Adapters. Many optical designs that advertise themselves as "astrograph" quality actually only produce pinpoint stars across a curved focal plane. Shop focal reducer and corrector accessories like this Sky-Watcher Evostar 80ED. 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. Sky-Watcher GoTo Dobsonian and EQ Mount SaleĮdgeHD is an aplanatic Schmidt telescope designed to produce aberration-free images across a wide visual and photographic field of view.Color Correction & Minus Violet Filters 0.5x focal reducer effectively halves the focal length of a telescope, enabling lower magnification, a wider field of view, and shorter exposure times for astrophotography Threads into eyepieces, camera adapters, and other accessories with standard M48x0.Correctors, Focal Reducers & Flatteners What is the difference between the Celestron Focal Reducer (special for Edge HD) and others I see there is an older version of this focal reducer by Celestron as well, but I understood this is not compatible with the Edge HD series There are other brands as well (Optec.
