ZWO Electronc Filter Wheel (EFW) 7 x 36mm-II

New 7 x 36mm Filter Wheel Larger than old model Mounting holes for Tilt Plates and adapters 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.
