The ZWO tilt adapter (M54) features an M54 threaded connection, compatible with devices such as the ASI 2600, ASI 6200, ASI 2400 cameras, as well as the ZWO EFW 7 x 2" filter wheel.
The tilt adapter allows for fine adjustment of the camera's tilt angle, enabling correction of minor deviations relative to the optical axis. An advantage is that it can be adjusted from the rear, meaning the adjustment screws remain accessible even when assembled with a filter wheel, filter drawer, etc.
Note: The ZWO tilt adapter (M54) is not compatible with the OAG-L product.
(The camera is not included with the product; it is shown in the product photo for illustration purposes only.)
