Independently designed by ZWO with a 21 mm ring configuration, this Filter Drawer is compatible with 2" filters and features M42x0.75 external camera side thread and M48x0.75 internal filter end and telescope side thread.


With the ability of double strong magnetic adsorption, it is more convenient and much easier to install or pull out the filter. There is a lock screw on the side of it. The locking function is helpful on adjusting the tension to eliminate the gap, which is a double insurance for users.

The filter drawer also comes with the M48-M42 adapter. You can use it with your camera or your telescope.

ZWO 2" Filter Drawer

I wanted to use 2" filters for my CCD camera but did not want to use a cumbersome full size filter wheel. Since I preferred to use mainly 2" Red CCD filters I choose the 2" filter drawer from ZWO. With a 2"-1.25" adapter I can also use 1.25" filters. I could manually change filters when required. The filter drawer(21mm) with M42/T2 connections attached directly to my CCD camera(13mm) and with a M42/T2(21mm) extension adapter connected directly to my reducer flattener to give the correct back focus(55mm)
