Sam, just so you know the new mask sent have issues. They're to big and the sides of the mask overlap the mask mounted next to each other. We've already tested this type of mask were the sides overlap, which still allow light to leak underneath. The good thing with your mask is them being made from a pastic type material. This adds rigidity, if we cut the overlap out they may accomplish the goal and lay flat against the wheel. The 3 tabs for the screw mount is perfect but reducing the outside diameter to fit within the filter area, in my case 36mm, would prove most beneficial easest

thanks for the feedback

yes, we know there is overlap and we thought it should stop the light

but seems we were wrong

we will try to fix in the future

and provide better screws

Hello Sam, how are the masks for 31mm filters?

If possible, you can attach a .DXF or .STL drawing to be able to 3D print the masks myself at home.

regards

Julio.

we think only 36mm filter would have such problem as the light may leak from the edge

we make some mask to come with the 36mm EFW to solve this problem now

but 1.25" filters should be OK as there is filter mount

Sam,

I bought the 1600mm with efw and 36mm package lrgb and narrowband. My filter wheel came with the new masks and I have the same issue as the above posters. My camera is only 4 months old. Has a filter fix been made to solve this issue or replacements? can I get an extra set of masks so I can try to trim them to sit flat? or have better masks been made?

Thanks,

Dean

If masks already used on the filters, I think the filter is not cause the issue. The reflection of inside(extenders or adapters) maybe cause that.

Hello Sam, how can I get the masks for a 31mm filter, I've seen them in this photo.

Or I can also use the Autocad .dwg or DXF plane and I can print them myself in 3d, I have some ring problems in my flats images.

The 1.25 filters ARE NOT okay. I have posted flats in the thread referred to above (posted by Kaos). The flats CLEARLY show the ringing artifices in the ZWO 1.25 filters because they are improperly coated. I get horrible rings in my lights & flats with the ZWO 1.25 filters. I removed the ZWO filters and replaced them with Meade LRGB filters and the flats look normal with no ringing artifacts! That should tell you that the ZWO filters are the cause of the problem.

My ZWO filters are not coated to the edge and neither are the edges darkened. This creates horrible reflections. Mr. Sam, please try addressing the issue with the 1.25 filters instead of ignoring it. I will be happy to provide you copies of the test flats. You can see them if you will simply go to the Cloudynights thread referred to.

Hi Kaos

Thanks for your reply. Our 31mm and 36mm edges darkened, 1.25" filter has a mount, so I think the edge is coverd by mount, but we will check if there is any other part cause the reflection, thank you so much!

when will you be able to send me a set of 7 of these masks? Right now, I basically dont have any ability to take good data. Also there is at least one user out there with 31mm filters that also has reported having this problem.

Please send a email to info(at)zwoptical.com asking for it, we will help you get it.
