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.
