Starizona Hyperstar for Celestron 8" SCT/Edge HD Telescopes
- For use with Celestron 8" SCT and Edge HD Telescopes
- Wide-field of view imaging
- Short exposure time
- Easy no-tool installation
Starizona's HyperStar optical system is based on Celestron's innovative Fastar feature which allows the secondary mirror to be removed from Celestron's Schmidt-Cassegrain or Edge HD telescopes. The HyperStar lens assembly is fitted in place of the secondary mirror, and a CCD camera can then be mounted at the front of the telescope for a wider field of view andfaster imaging. The HyperStar systems allows an 8" SCT or Edge HD telescope to operate at a focal ratio of f/1.9, which is an incredible 28 times faster than the standard f/10 focal ratio meaning that images can potentially be obtained in just seconds!
Switching from the HyperStar to the telescope's normal f/10 optical configuration, and vice versa, is simple and fast. The swapping takes only a minute or two, is a no-tool operation, and as the telescope's secondary mirror is indexed, no recollimation is necessary.
The HyperStar lens assembly works with a variety of cameras from Atik, Orion, Meade, Mallincam, SBIG, Starlight Xpress and more. Different cameras require different adapters in order to preserve the required critical back-focus distance of the HyperStar lens from the imaging sensor. One adaptor is included with the HyperStar lens. Please specify the camera being used when ordering.
A holder is included for safe storage of the secondary mirror while imaging.
Please see the video below for a nighttime demonstration of the use of the Hyperstar.
