Sounds like your adding another string to the bow there Asi.

Asi, years ago I experimented with a whole plethora of masks and one that produced interesting results was off axis.

Might be interesting to try a mask with the largest off axis hole you can cut that uses a section of your primary from its outer edge to the edge of your secondary to give you a totally unobstructed light path. You probably have already tried this but if not.....
