The ZWO Filter Drawer (Mark II) is a simple, practical alternative to a filter wheel. It lets you swap 2" filters quickly without removing the camera or disturbing your setup.
The drawer attaches to the camera via a T2 thread. On the telescope side, it features an M48 thread, and with the included M48/T2 adapter it can also provide a T2-thread connection.
With an exact width of 21 mm, the ZWO 2" filter drawer replaces a 21 mm T2 extension when used with ZWO cameras. The product includes one 2" filter drawer, with additional drawers available separately. An optional 2"/1.25" adapter also allows the use of smaller filters.
The lightweight yet rigid design uses a magnetic lock to hold the filter drawer securely in place, while its matte black surfaces effectively suppress internal reflections throughout.
Compared to the previous version, the Mark II improves the connection between the drawer and the holder to prevent stray light from entering. Two small “wings” on the drawer sit flush against the housing of the drawer holder.
