The FD-CANON Filter Drawer is compatible with all ASI camera that have a 17.5 back focus, except the ASI GT series cameras.  The drawer opens to accept 2" filters, and has been tested with the ZWO brand. If you use filters by manufacturers other than ZWO, remember that threaded 2" filters must be less than 7.5 mm in thickness (not including the threads) and less than 50.8 mm in diameter.  The thread itself must be less than 2.7 mm thick.

Double strong magnetic absorption makes it easier to install or remove the filter drawer.
