Sun

Used Seestar S30 Pro.

-captured video frames (about a 10 second clip),

-processed this in PIPP (Planetary Imaging PreProcessor) which output an AVI,

-then imported into to AutoStakkert! which outputed a stacked linear image,

-then imported into Siril: cropped 16:9, basic Histogram Transformation to remove banding around sun, then conservative use of wavelets control to sharpen the sunspots a little.
