Starizona HyperStar C8

The HyperStar for C8 has been designed based on the innovative Fastar feature of CELESTRON's traditional SC tubes. This feature allows easy removal of the secondary mirror of CELESTRON Schmidt-Cassegrain telescopes that are compatible with Fastar systems (indicated on the front of the tube, just in front of the secondary mirror). By installing the HyperStar lens in its place, a CCD camera can be attached to the front of the telescope allowing a wider field image to be captured and the possibility of much brighter astrophotography.

Removing the HyperStar to return to the telescope's original f/10 setting is simple and quick. It only takes a minute or two, does not require the use of tools, and since the secondary mirror has a marking that makes its position unique, the telescope does not need to be recollimated.

The HyperStar lens system works with a wide variety of cameras, such as the ATIKoRION, MEADE, MALLINCAM, SBIG, STARLIGHT XPRESS and many more. Each camera may require a different coupling adapter to preserve the HyperStar's critical backfocus distance.

An adapter is included with the order of a HyperStar system. Please specify the camera to be used at the time of ordering.

A stand is included so that the secondary mirror can be safely stored while the HyperStar is installed.

The HyperStar system allows the CELESTRON 8" telescope to operate at a focal ratio of f/2.1, thus some 23 times faster than working with the original f/10!! configuration Fantastic images can be obtained in just a few seconds only!!!!
