ZWO Filter Drawer for Canon EOS Lens – 2" Filter, M42 Camera

ZWO Filter Drawer for Canon EOS Lens – 2" Filter, M42 Camera

DESCRIPTION

The ZWO filter drawer for Canon EOS lenses lets you insert a standard 2" screw-in filter (M48 thread) between your lens and ZWO astronomy camera. A magnetic locking drawer ensures easy, repeatable filter swaps while maintaining proper spacing. Designed for cameras with a 17.5 mm backfocus (like most ZWO models), it guarantees perfect focus when combined with EOS lenses. The adapter is CNC-machined from black anodized aluminum for light suppression and mechanical reliability. Ideal for lightweight astrophotography setups or remote use.
