SOLD HIRSCH F6.3 FOCAL REDUCER / CORRECTOR
Fits any Schmidt-Cassegrain telescope with a 2 inch visual back. It’s a 4 element coated lens and reduces an f10 telescope to f6.3 as well as flattening the field. There is plenty of discussion on the web about the differences between Meade, Celestron, Hirsch and Antares reducers, most conclude they are all from the same factory or factories (Japan, China and Canada) depending on when they were produced. . So no more discussion or posts about it here please.
This one is well finished and in excellent condition.
