About
A fully multicoated dual-element zero-power field flattener for refractors between f/6 and f/8, leaving focal length and focal ratio untouched while sharpening stars to the corners of a DSLR or large-format CCD frame. Its 2" barrel slips into the focuser, and since August 2021 it ships with threaded adapter tops for either 42 mm or 48 mm T-threads.
