I'm trying to find the proper way to mount/secure unmounted filters in the QHY filterwheel. They don't come with masks, instead they come with these cardboard washers and screws. Question is the best way and proper way to secure the filters. Do the little washers sit on top of the filters to hold it down or are they use to press up against the filter to hold it in place.
If someone knows, please share and a photo or two would be nice.
Thanks
