Compression Ring Visual Back for Orion Crayford Focusers
This precision machined compression ring type visual back replaces the
factory thumb-screw type back that comes on Orion's Crayford type
focusers, including the two-speed. While protecting your eyepieces or
accessories from marring, the brass compression ring also provides
more secure retention.
If the male threads on your factory visual back measure 2.13" then
#FAC2 should fit.
Made from black anodized aluminum with a brass compression ring and
nylon thumbscrews. Weighs 1.7 oz.
