The new ZWO EFW 7 x 36-II (Electronic Filter Wheel) was independently developed by ZWO for astronomical mono cameras. With the larger body and the newly-added screw holes on the covers, it will give a much easier and more fixable way to connect to ASI cameras.

There are 7 slots inside the EFW 7 x 36-II and we recommend you use the ZWO 36mm LRGB and SHO filter set with it.

The body is CNC milled from an aircraft-graded aluminum block. It is made of high quality and thin with a thickness of only 20mm. The heart of the EFW 7 x 36-II uses quality stepper motors produced by NPM, Japan, which are very reliable. When photographing, you can rotate the EFW in both counterclockwise or clockwise directions for filter selection. The whole operation process is rather convenient and efficient.

ZWO EFW 7 x 36 - II

Compared to the original 36mm EFW, you may find the new ZWO EFW 7 x 36-II has a bigger size. The screw holes on the front and back covers shall not only allow us directly connect the EFW 7 x 36-II to the camera and bring the filters closer to the camera sensor but also make it possible to match it with M68 OAG.

ZWO EFW 7 x 36 - II

All ZWO 36mm filters can be perfectly supported by this EFW. But if you use filters from a third party, then please make sure the thickness of the filter should exceed 1.8mm.
