Starizona Hyperstar voor C11 standaard of Fastar

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!

Focus is achieved using the standard focus knob on the telescope (moving the primary mirror) . The image is seen on the computer screen via the CCD camera, so focusing is very easy. Autofocusing is also possible using a motorized focuser such as Starizona's Wireless MicroTouch Autofocuser. Despite focusing with the primary mirror rather than a Crayford-type focuser, mirror shift is not an issue. Remember that the image from the primary mirror in an SCT is normally magnified 5 times by the secondary mirror. With HyperStar, the secondary is removed so any mirror shift is reduced five-fold. The field of view is so wide with HyperStar that any image shift is not an issue.
