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! Specifications Focal Ratio: f/2 Focal Length: 300mm Maximum Usable Sensor Size: 28mm Diagonal Camera Adapter Threaded for 2" Filters Backfocus (from mounting thread to focal plane): 39.8mm (1.567") Length (without camera adapter): 3.3" Diameter: 2.8" Weight: Less than 1 lb.
