I’ve recently been watching Adam Blocks tutorials on masks and I’ve had an idea on how to remove circular patterns like this.

Create a circular mask that is the same size of the circular patterns. Create a star mask and subtract any stars from within that circular mask. This should create a mask that covers the rings and not the stars. Invert the mask and use a high MMT and it’ll average everything in there.

It’ll keep the Starr’s but remove the rings and diffraction spikes.
