Hyperstar 6

HYPERSTAR 6
This fits a Celestron C6 SCT, it's in perfect condition.
Backfocus (from mounting thread to focal plane): 44.3mm (1.74")
Comes with two spacers 26.85mm and 31.85mm suitable for ZWO or similar cameras. An 1 1/4" filter can be screwed into the M42 adapter or the shorter spacer can be used if a filter draw is to be inserted into the train.

MANUFACTURERS 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!
