Starizona HyperStar C8 v4 (Pre-owned)

The HyperStar 8 lens converts a standard Celestron 8" SCT from f/10 to f/1.9, making the system 25 times faster. That means 25-times shorter exposures! Now you can capture deep-sky images without guiding and without an equatorial wedge (in alt-az configuration). The HyperStar lens shortens the focal length of the telescope, giving a much wider field of view, and giving a greater tolerance of tracking errors, allowing for unguided, alt-az imaging.

The HyperStar 8 is compatible with a variety of cameras, including CCD, CMOS and DSLRs. The HyperStar 8 covers up to a 28mm sensor size. Separate adapters are required for different cameras. One adapter is included with the HyperStar lens.

Optical performance is excellent, with a coma-free, flat field of view up to 4.1 degrees wide.
