Product Description

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.

Note: This is the NEW design of the filter drawer, which has an improved anti-light-leaking design, double-strong magnets, and a lock screw.

ZWO Filter Drawer for 2" Mounted Filter (ZWO-FD-M42-II)?

Works great

Simple and functional

Does the job fine. The reduced magnetic catch works much better than previous model because it allows removal of filter drawer without inadvertently moving the telescope 👍

Works great, worth the investment.

One of the better investments I've made in awhile for my setup. It's nice not having to go outside to focus.
Its easy to install and set up on my Celestron 8 edge HD. The first couple focus routines, I dialed in the backlash, and after the 3rd maybe 4th autofocus sequence, I had a nice v-curve.
Now I need another for my refractor.
