I recorded the Sun in UV using the automated filter wheel and the EQ3-mod, mountpusher, Baader Astrosolar ND3.8 Film, TS-Optics 76/342 TS76EDPH, Baader Venus U filter 1.25″, ASI 178MM (cooled) setup. The false color picture below was obtained from 6x 4’33 exposure, almost 500GB raw data, give or take. Active regions (brighter than their context) have been emphasized. For reference, I included the registax-output too, which is a the stage before applying the content aware emphasizing and the false color.
