It was a nice idea Rick & Evan, both do a very good job at removing the banding but it does also begin to "correct" things that aren't there. Kinda like bad flats.
Although it works exceptionally well in the lower parts of the image where there is a real poor signal (the banding is at its strongest), it causes gradients in high signal areas where picking up a "background" is impossible.
Both of these images have been processed identically except one has has banding removed and the other hasn't. On the left most panel you can see that the dusty regions at the top are near black and almost bended in down the bottom. The mismatch between the images in intensity was so bad that PI couldn't register two of the panels.
I am beginning to think that I may just have to deal with what I've got which has been attached (pre editing).
