Description
HyperStar is based on Celestron’s innovative Fastar feature. This feature allows the secondary mirror to be removed from Celestron’s Schmidt-Cassegrain telescopes. By mounting the HyperStar lens assembly in place of the secondary mirror, a CCD camera can be mounted at the front of the telescope allowing for a wider field of view and much faster imaging.
The HyperStar lens assembly works with a variety of cameras. Different cameras require different adapters, however. One adapter 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.
The HyperStar systems allows the telescope to operate at a focal ratio of f/2, an incredible 25 times faster than the standard f/10 focal ratio! Images can be obtained in just seconds!

FAQs
Do I need the Filter Slider to use Filters with the HyperStar?
No, the standard camera adapter that comes with the HyperStar allows the use of one 2” mounted filter. This is ideal for light pollution or IR/Cut filters when using a one-shot color camera. Although, the Filter Slider is ideal for quick filter changes when using a monochrome camera.
Are HyperStars hard to focus?
HyperStars are no more difficult to focus than any other optical system. HyperStars can be accurately focused with Bahtinov Masks, AutoFocusers (ie MicroTouch Autofocuser), and any software that displays a Full-Width Half-Max star value. Although, the fast F/Ratio does make the camera’s backfocus much more critical. This is why the HyperStar camera adapters need to be precisely within +- .5mm of the camera’s backfocus.
Why do I need to specify my mount type?
We ask for the mount type to determine if you’ll need a counterweight shipped with your HyperStar or not. GEM mounts can accommodate the balance of the HyperStar by shifting the scope forward or backward on the mount, whereas Fork Mounted telescopes can’t move on the mount and require a counterweight.
