The ZWO M54 filter drawer is designed to work with full frame cameras without experiencing any vignetting. It allows to manually change a 2" filter with the standard M48 x 0.75 male thread. Two magnets secure the draw and a grab screw adjusts its tension.

The M54 x 0.75 female thread can be used to connect the drawer to a telescope. The M54 x 0.75 male thread can be used to connect the drawer to the ASI 6200 cameras.

This solution produces a backfocus of 56mm, which when a standard 3mm thick filter is used, the effective backfocus will be 55mm.
