HyperStar is Starizona's improved version of Celestron's Fastar lens. Fastar optics allows the secondary mirror to be removed from an SCT and replaced with a lens assembly that allows fast f/1.8 imaging. The HyperStar lens has better optical correction than the original Fastar and is compatible with many more CCD cameras. It is available for Celestron's 8", 11" and 14" Schmidt-Cassegrain telescopes.
