About
A 1× field flattener for the 130 mm Astro-Tech triplets that leaves them at 910 mm f/7 and corrects the field over a 60 mm image circle — the largest in the family, with headroom past full frame. Threads into the M92 drawtube and offers three camera-side threads, with internal 2" filter threads under the top optical cell.
