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.
The software was developed together with PlaneWave Instruments and enables a highly accurate GoTo control. The PointXP Mount Modelling, which is also used in the Celestron StarSense module, is used for this purpose, and allows a much more accurate model of the sky than the electronics of a hand control box. Various reference stars are used to compensate for numerous types of alignment errors including telescope flexing.
Besides the higher accuracy, control via a PC/laptop combined with the stored star chart is particularly simple and intuitive. In addition, the PWI software has a larger object database than the manual control. If you have Internet access, PWI can even access the SIMBAD professional astronomical database.
The PC/laptop is connected via USB 2.0. The PWI software runs on Windows 7, 8, and 10.
