ZWO Canon EOS Lens Adapter for 1.25" EFW Filter Wheel - EFW-EOS-II Celestron Telescope Accessories 2” adapterThe ZWO EFW EOS adapter was designed by ZWO in order to connect a Canon EOS EF lens (not EF S) with a ZWO 1. 25 31mm 36mm filter wheel. The short adapter takes up 17. 5 mm of back focus and can only work with ASI cooled cameras with 6. 5 mm back focus, such as the ASI533, ASI183, ASI294 and ASI1600. The thread of the interface is M42*0. 75 and so therefore does not fit the 2" EFW electronic filter wheels.
