Dear ZWO, I am Simone Curzi, your happy customer. I own your ZWO EFW 7x36mm, it was sold to me together with ZWO filter masks, they are perfectly circular, which once mounted are too wide and overlap with the adjacent filter mask. The ZWO filter mask for sale on your site (at https://astronomy-imaging-camera.com/product/zwo-filter-masks/) are like this picture (https://astronomy-imaging-camera.com/wp-content/uploads/Filter-Mask-2.jpg) or cicular? I need the version as in the picture, but no Italian dealer has them . clear skies Simone
simonecurzi81 36mm EFW should not have this problem, i just checked the EFW at my end, the filter mask does not overlap.

Do not use the masks from ZWO. 3D printed filter masks on 7x36mm EFW:

simonecurzi81 No, the picture is the filter mask for the 31mm filter. We did not change the design of 36mm filter mask, but we released a new version 7*36mm EFW that add the screw holes to connect OAG-L and camera, and larger size to solve the mask overlap problem. https://astronomy-imaging-camera.com/product/new-zwo-efw-7x36mm/
