This is an R-RGB image of Mars and my best ever Mars image to date. The capture sequence was 5 sets of R-G-B-IR AVIs, each of 3 mins duration at 75 fps, however, with the R data being good, I opted to use the stack of 5xR as a luminance rather than the inferior resolution IR data.
I processed each of the 5xRGB AVIs in AS3!, taking each stack of best 30% into Registax 6 for wavelet sharpening, before de-rotating in WinJupos. The final de-rotated R-RGB stack had a further mild sharpening and colour balance adjustment in Registax 6, followed by a few aesthetic tweaks in Affinity Photo and PS, where I also added the annotation.
