- Adjust opacity as required
This may help with the banding.

What I had originally in mind was using PS and selecting the banded regions (the bluer ones) and just selectively playing with the colour. Not sure if my computer will like doing stuff to a 17gb .psd file
More food for thought though.

GoodLook 64's Displayer has a "Corduroy" button which does a pretty good job at removing patterned read noise banding. It has to be done on the individual frames before assembling the mosaic, because in general the bands won't line up from frame to frame.
The bands need to be horizontal. If they're vertical, rotate the image 90 deg, then de-corduroy, then rotate back.
Be interested to know if it does the trick on your image, but it should. Doing 90 panels one at a time could require some fortitude, but each panel is very quick.

Should this be done on the linear data (as the very first process) or at the end after manipulation?
