William Optics 2" APO Apochromatic Field Flattener

by Legacy Reviewer, Verified Owner Written on June 17, 2008
Finally a top-quality astronomical accessory at affordable price!
William Optics 2" APO Apochromatic Field Flattener and 0.8x Focal Reducer is really astonishing.
I use it with my 2.5 inches APO refractor telescope and it makes the field correct and flat up to the edge of a DSLR camera CCD-frame.
Safe transport and fast delivery time!
Very Good!
