ZWO M42 Filter Drawer for 2" Mounted Filters - Gen II - FD-M42-II

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 absorption, 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 and is not compatible with previous version of the filter holder.  The proper filter holder is the F-HLDR.
