A Seestar S50 was used to capture 3 minute RAW AVIs either Through a Baader OD 5.0 solar filter, or an OD 5.0 filter and a Baader Ca K-line filter, controlling the brightness and exposure in the software. The best 60% of the frames in each AVI were debayered and stacked in Autostakkert!4. The images were wavelet processed in waveSharp 2.0 and post processed in the Gimp 2.10 and ACDSee.
