Does exactly what it is supposed to.

I’ve got large Riccardi flattener/reducers that terminate in M68 or M82 adapted to M68. This adapter takes me to M54 which is the interface used by my Starlight filter wheel for larger sensors. Does what it is supposed to without using a lot of backfocus. Very solid piece.
