ZWO CAA Camera Rotator Plate M42
The popular ZWO CAA-M54 Camera Angle Adjuster comes with M54 and M48 adapters on the camera side. However, many customers have been asking for a similar M42-threaded adapter to allow older types of ZWO cameras or with the use of ZWO's 36mm filter wheel with the CAA.

The ZWO CAA Camera Rotator Plate M42 is a dedicated adapter designed to expand compatibility for users of the ZWO Camera Angle Adjuster (CAA). While the standard CAA includes M48 and M54 adapters for use with most modern cooled ZWO cameras, this camera rotator plate M42 is specifically made for setups requiring an M42 connection, such as older ZWO cameras or the 36mm Electronic Filter Wheel (EFW).
The zwo camera rotator m42 provides a secure M42 male thread on the camera-facing side, enabling seamless connection with ZWO cameras or accessories that require an M42 thread interface. This is particularly useful when working with legacy imaging gear or specialised filter wheels that are not compatible with the larger M48 or M54 threads. Importantly, the ZWO CAA Camera Rotator Plate M42 adapter maintains the correct optical 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
Installing the camera rotator plate is quick and straightforward. Simply remove the default adapter from your CAA unit and replace it with the M42 plate. No additional spacers or adapters are needed, making it a clean and stable solution for adapting to older or specialised setups.
ZWO CAA Camera Rotator Plate M42 offers full camera angle rotation functionality while preserving optical performance and spacing accuracy for all m42 threaded components.

Q1. What is the ZWO CAA Camera Rotator Plate M42 used for?
The ZWO CAA Camera Rotator Plate M42 allows users to adapt their ZWO Camera Angle Adjuster (CAA) to work with accessories or cameras that require an M42 thread, such as older ZWO models or the 36mm Electronic Filter Wheel.
Q2. How does this camera rotator plate differ from the standard CAA setup?
The standard CAA includes M48 and M54 adapters. This camera rotator plate M42 replaces the default adapter, providing an M42 male thread on the camera-facing side to support legacy or M42-threaded gear.
Q3. Will installing the ZWO CAA Camera Rotator Plate M42 affect my backfocus?
No. The zwo camera rotator m42 is designed to maintain the correct 55mm backfocus when installed, ensuring your imaging train stays optically aligned and within specification.
Q4. Is the M42 camera rotator plate compatible with all ZWO cameras?
It is specifically intended for ZWO cameras and accessories that require an M42 thread, particularly legacy models. Modern cooled ZWO cameras with M48 or M54 threads do not require this adapter unless you're using M42-specific accessories.
Q5. Does this camera rotator plate still allow for full rotation adjustment?
Yes. Replacing the adapter does not affect the rotation function of the CAA. You can still freely rotate your camera to adjust framing without impacting your telescope’s focus or alignment.
