This adapter allows you to connect Nikon F-mount lenses to the ZWO EFW and EFW Mini 1.25", 31mm & 36mm filter wheels and accessories that use an M42 thread such as the ZWO M42 filter drawer. The adapter provides 20mm of optical thickness and the thread is M42 x 0.75, so it cannot be connected to the 2" EFW.
Suitable for ASI cameras with 6.5mm back focus and sensor 1" and 4/3 in size such as the ASI533, 183, 294 & 1600.
Note: the sensor tilt adapter needs to be removed before you connect the camera to the EFW 2" filter wheel.
