The ZWO CAA Camera Angle Adjuster is widely used for precise camera rotation without disturbing your imaging setup. By default, the CAA includes M54 and M48 adapters to suit most modern ZWO cooled cameras. However, users working with legacy ZWO cameras or using accessories such as the 36mm Electronic Filter Wheel (EFW), which features M42 connections, often face compatibility limitations.

This dedicated ZWO CAA Camera Rotator Plate M42 solves that issue by providing a secure M42 male thread on the camera side, allowing seamless integration with older ZWO cameras or accessories that require an M42 connection. Importantly, this adapter maintains the optical path's spacing and does not alter the required 55mm back focus, ensuring your imaging train stays precisely within spec.

How to attach the M42 Adapter to the CAA

Whether you're upgrading an existing setup or adapting older hardware, this M42 adapter offers a reliable, non-intrusive solution that expands compatibility while preserving your critical back focus distance.
