The equipment
AstroDMx Capture was used to capture 2 x overlapping RAW 1500-frame SER files of the Sun.
The best 75% of the frames in each SER file were debayered and stacked in Autostakkert!4, The two resulting images were stacked in ICE and then wavelet processed in waveSharp and further processed in Gimp 2.10, G'MIC and ACDSee.
