The ZWO Gen 2 M42 x 0.75 Filter Drawer is a refined and reliable filter management solution tailored for astrophotographers using 2" filters. This second-generation drawer features an improved magnetic design for secure filter holding and effortless swapping in the field. Its ultra-slim, lightweight profile minimizes added backfocus while maintaining mechanical precision.
Threaded with standard M42 x 0.75 connections, it seamlessly integrates with most ZWO cooled cameras, ASI accessories, and imaging trains. The internal cavity is precisely CNC-machined to reduce internal reflections and optimize contrast, making it ideal for use with narrowband filters in deep-sky imaging workflows. For imagers who prefer manual filter switching without a full electronic wheel, this drawer offers the perfect balance of control and simplicity.
