Product Description
ZWO 2-inch Filter Drawer with 21mm ring design is independently developed by ZWO, which includes M42 * 0.75 male thread (camera side) and M48 * 0.75 female thread (filter end), M48 * 0.75 female thread (telescope side) as well.
The double strong magnets create stronger adsorption, easier installation and pulling out. 
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.
With the ability of double strong magnetic adsorption, it is more convenient and much easier to install or pull out the filter.
The filter drawer also comes with the M48-M42 adapter. You can use it with your camera or your telescope.

How to you fix the M48-M42 adaptor to stay in place?
Right now, I do not have a filter to test the drawer, but I can screw the adaptor all the way in, and lose it inside the drawer.
How does it stay fit and strong?

Hello, I heard you are changing design of the filder drawer/holder that should be available from May. Will the current filder holder still fit the new drawer? I wanted to buy second one simply to change filters between 2 telescopes and now with new design it is questionable. Please advise. Thanks

I have a 183mc pro, EAF and ASIAir Pro and they are brilliant products.
My question is about the ZWO Filter Drawer (M42). Can you fit a 1.25in filter into this drawer using an adapter
of some kind. It would save me having to remove the camera to fit a new filter and keep the camera orientation
the same.
Many Thanks

Hoo Dat – :
Can I use this along with the Canon EOS T-2 adapter (which I recently bought from you) to place a 2 inch filter between my Canon lens and a ASI 2600mc, or do I have to buy the Canon EOS filter drawer?
If this would work, I would rather buy this, because then I could use it on other telescopes also.

Just to be sure, this will accept the 2″ IR-CUT filter? I am looking to use my 071MC with the OAG and need to thread-in the adapter which prevents me from attaching the IR-Cut filter.
Thank you in advance
