Description

I find these full disk solar images to be super hard to process. I took 2000+ images originally, but ended up stacking only 25 images.
I tried a whole bunch of different stacking parameters, but I couldn't avoid stacking artifacts. The more images, the more artifacts.

Even the stack of 25 required extensive manual cleanup, including cleaning up heavy artifacts on the limb by rotating the image and pasting over the artifacts.
If you have a close look at the limb, you can probably see where it's been touched up. In any case, the face of the sun, including the sunspots, required very little manual cleanup.
