This reducer (~6 months old) is for Telescopes with flat field like Meade ACF, GSO / Officina Stellare RC / Apo refractors with built in flattener. Going for $190.
The Optec Lepus 0.62X is a 4-element telecompressor designed by Optec engineers to work with newer, well-corrected Schmidt-Cassegrain telescopes such as the Meade ACF and the Celestron EdgeHD series telescopes.
