ZWO EFW-NIKON Adapter for EFW and ASI1600 (ZWO-EFW-NIKON-II)

The ZWO new EFW-Nikon-Ⅱ adapter with 20mm thickness design is independently developed by ZWO. It’s suitable for connecting Nikon lens and ZWO 1.25”/31mm/36mm filter wheel.

With an M42x0.75 thread, it fits perfectly on the 2" Electronic Filter Wheel from ZWO and then matched only with ASI cooled cameras that have a 6.5mm back focus length, like the ASI1600, ASI533, ASI183, and ASI294 cameras.
