This Series 4000 combination focal reducer and field corrector lens works with all Schmidt-Cassegrain telescopes with 2-inch visual back making it possible to have a dual focal ratio instrument, without sacrificing image quality. The reducer / corrector is f6.3.
This 4-element, fully-multi-coated lens provides a much wider field of view for astrophotography reducing exposure times by a factor of 3 and the results are amazing both visually and photographically.
Purchased from AstroShop. Never used as it wasn't compatible with my Mak (not a SCT).
$120 AUD.
