The Starizona HyperStar v4 - 11" Celestron EdgeHD and Filter Slider converts a standard Celestron 11" 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 11 is compatible with a variety of cameras, including CCD, CMOS and DSLRs. The HyperStar 11 covers up to a 35mm sensor size. Separate adapters are required for different cameras. One adapter is included with the HyperStar lens.
