This adapter allows you to connect Nikon F-mount lenses to the ZWO EFW 2" filter wheel and accessories that use an M54 thread such as the ZWO M54 filter drawer. The thread is M54 x 0.75, so it cannot be connected to the 1.25", 31mm or 36mm EFW.
Note: the sensor tilt adapter needs to be removed before you connect the camera to the EFW 2" filter wheel.
