Hi Peter,

I examined some of my processing files and found the donut issue arises only when Ha is combined with RGB when creating a synthetic luminance. The separate, combined RGB and Ha stacks don’t have this issue at all. So most likely about the tightness of the Ha data compared to the looser RGB data. Not sure of a solution other than blurring things out or maybe shrinking stars in the RGB data before making the synthetic luminance? Would love to hear fof possible solutions.

Until then I claim artistic license and suggest the stars be viewed like falling snow flakes on the darkened tree...
