About
A 0.8× focal reducer and field flattener for an 80 mm f/7 refractor, taking it to f/5.6. It either slides into a standard 2-inch adapter or threads into the former Stellarvue Access 2.5-inch focuser. The camera end takes a standard 42 mm thread and the opposite end carries a 2-inch filter thread, so a 2-inch filter can be screwed in for imaging.
