Jeff, great set of images. 

 

Am considering trying out Pixinsight as a processing step after IMPPG.  Exactly what features of Pixinsight do you normally apply after IMPPG?

For the Ha disc:  I stitch the stacked frames in Affinity first.  Then I sharpen disc in IMPPG, then use SolarToolbox as next step.  I adjust levels, contrast, color all in one place.  I have been experimenting also with using light applications of blur exterminator and noise exterminator with some success.  Blur exterminator needs a range mask so you are just working on the disk as it can do weird things to the background.   

On CaK, i follow same roadmap, but the color default in solar toolbox you can load a CaK palette.  I also use a bit less contrast on these

On WL, same pathway, but no color in the toolbox.  

If I do my sharpening in Imppg, I generally don't do more in toolbox.  

I am finding that noise exterminator does a good job of a final touch on some of these (not the CaK).  I have the amount set pretty low at 0.25 and detail down to 0.10.  I have not had good luck using the denoise function in toolbox.  

I also liberally use clone stamp as I get some stitching artifacts from Affinity

Hope that helps.
