Processing

AutoStakkert!3: stack, using 1.5 pixel vertical and horiztonal blur (Advanced>Experimental Features) to avoid grid pattern artifacts

Pixinsight:
Multiscale Linear Transform for wavelets (with a second less aggressive version to capture the polar cap)
Resample 200%
Curves: balance color for IMX224 sensor
Deconvolution
TGV Denoise
Curves: boost saturation in bright areas
Histo Trans to brighten

Photoshop:
Layer together main image and version with SPC, using masks
Paint out any bright speckles along limbs left over from WinJupos derotation
