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.
Switching from HyperStar to the telescope's normal f/10 configuration is simple and fast. It takes only a minute or two, requires no tools, and the telescope's secondary mirror is indexed so 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 critical backfocus distance of the HyperStar lens. 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 an 11" telescope to operate at a focal ratio of f/2.0, an incredible 25 times faster than the standard f/10 focal ratio! Images can be obtained in just seconds!
Check out the HyperStar Website for more details and images taken using the HyperStar system.
- Focal Ratio: f/2.0
- Focal Length: 560mm
- Maximum Usable Sensor Size: 27mm Diagonal (APS Format)
- DSLR Compatible
- Field of View (with 27mm sensor): 2.9 degrees
- Camera Adapter Threaded for 2" (48mm) Filters*
- Backfocus (from mounting thread to focal plane): 59.7mm (2.35")

Select the camera model you will use below. The HyperStar includes one camera adapter of your choice.
Select the version of secondary mirror housing you have below. If your telescope is a CPC series with a factory-installed Fastar secondary mirror, choose the first option. If your telescope is a NexStar GPS with factory-installed Fastar secondary mirror OR any Celestron which has been converted using the Starizona HyperStar Conversion Kit, choose the second option.
Select the telescope mount you have below. If you have a CPC or NexStar fork-mounted model, select the first option. If you have a CGEM, CGE Pro, or an OTA on any other type of German Equatorial Mount, choose the second option.
