Holder for Filter Drawer 2"

The filter holder allows you to switch between different 2" filters in seconds without having to unscrew and screw in the filters. This protects the filters by preventing fingerprints and saves time. This filter holder/insert accepts mounted filters with a 2" filter thread and is compatible with the current ZWO filter drawers FD-EOS, FD-NIKON, FD-M42-II and FD-M54-II, as well as the previous generation FD-M54 and FD-M42 filter drawers.

Among others, all 2" Optolong, Baader, ZWO and Astronomik filters fit into this insert.
