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. In 12-bit mode, it produces 46. 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. As one of ZWOs latest OSC planetary cameras, it features a large sensor format of 1/1.2', a high resolution of 3840x2160, and a surprisingly amazing characteristic of ZERO AMP GLOW The pixel size is 2.9umx2.9um. Many optical designs that advertise themselves as "astrograph" quality actually only produce pinpoint stars across a curved focal plane. It threads onto the rear cell of 5 to 16 Celestron and Meade Schmidt-Cassegrain telescopes, making it possible to have a dual focal ratio instrument without sacrificing image quality. 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. Tech Details Reviews This focal reducer and field flattener consists of a four-element multicoated 40mm lens in a metal cell. For this I used 4 eyepieces, Pan 41 Pan 35 ES 34 68 and Agena Astro SWA38. 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.
