ZWO Gen 2 M54 x 0.75 Filter Drawer for 2" Filters
ZWO Gen 2 Filter Drawer with M54 x 0.75 Thread for 2" Filters
This second-generation ZWO M54 Filter Drawer features a 20 mm ring design and contains two strong magnets for more substantial adsorption and easier installation/removal. Compared to the previous version of ZWO's M54 filter drawer, this filter drawer features an improved seal to reduce the chance of stray light leaking onto the filter. This improvement is particularly important and noticeable over long exposures. A lock screw provides tension adjustment between the filter holder and drawer to eliminate any gap.
The ZWO Gen 2 Filter Drawer has an M48 x 0.75 female thread to be used with 2" filters, an M54 x 0.75 female thread for connection to a telescope, and an M54 x 0.75 male thread to connect to an astronomy camera. Compatible with the ZWO 2" Filter Holder (Gen 2). Suitable for 2-inch astronomical filters and full-frame cameras.
This new version of the ZWO M54 2" filter drawer is NOT compatible with the first-generation ZWO spare filter holder.
