Starizona HyperStar C925 EDGE HD

This model includes the adapter ring required to attach the HyperStar lens to the indicated Edge HD telescope model. To use this HyperStar with a traditional (non-HD) Schmidt-Cassegrain telescope, an additional adapter would be required.

The HyperStar for C925 HD has been designed based on the innovative Fastar feature of CELESTRON's new SC tubes. This feature allows easy removal of the secondary mirror from CELESTRON Edge HD telescopes. By installing the HyperStar lens in its place, a CCD camera can be attached to the front of the telescope allowing for a wider field image 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 9¼" CELESTRON EDGE HD telescope to operate at a focal ratio of f/2.3, thus about 18 times faster than working with the original f/10!!! configuration Fantastic images can be obtained in just a few seconds only!!!!
