I am headed back to a CFW.

Astronomik 12Nm Ha filter, in a T2 mount. Near new, in box. Can be used in the filter drawer, or right in the optical train, has T threads on both sides.
AU$260.

Gerd Neumann Filter Drawer.
Drawer has male T thread one side, female T thread on the other and is about 20mm thick. Uses slides and varying sizes are available. Includes the slide to accept T2 filters.
AU$160.

As a going concern, the drawer, slide, and Ha filter prove a perfect combination for a one shot colour camera user (QHY8 or the likes) to dabble in Ha imaging. This allows the camera to be mounted on the focuser, and filter changes made without moving the setup. The drawer can be left on all the time, and filter as and when required.
Via PM please. Prices do not include post.
