I've attached a screen shot that shows what I would be doing for colour balance while it is in the linear stage. I did try it on your JPEG but it didn't work in the slightest  I did notice that your background does have a blue hue to it, it isn't obvious mind you but it does show up in the histogram.
My only other suggestion would be to either not do as many iterations when running deconvolution OR to change your global dark/white so as to not get the "worms" on the edges of high contrast areas. If you look around the pillars it has a white rib, that is caused by the deconvolution.
Other than that, you've done an excellent job  |
Thanks for the comments Colin. I generated a synthetic luminance from the SHO data as suggested by RickS. I did 100 iterations of deconvolution (is that too many?) but then further sharpened luminance with a multiscale linear transform. Maybe that was where the worms came from...?
The (non drizzle) data is available at
