HyperStar is the easiest way to capture deep-sky astrophotos. The HyperStar* unit is a multiple-lens corrector which replaces the secondary mirror on a Schmidt-Cassegrain telescope and allows extremely fast CCD imaging. Depending on the size of the telescope, the resulting focal ratio will be between f/1.8 and f/2.0, up to 31 times faster than imaging at f/10! Removing the secondary mirror and installing the HyperStar lens is very quick and easy. No tools are required and switching between the HyperStar and regular f/10 modes of the telescope takes only a couple minutes. HyperStar provides the easiest and fastest means of imaging deep-sky celestial objects!
