Description

The two are too far apart for one image for me, so I put them in a mosaic. I think they make a good comparison, but very difficult to get the right levels and color balance.

After consulting with pfile, eventually what I did was to use masked stretch to the same median values for both non-linear images and then do the merge on these stretched images. I could not get the background levels right using linear images. Unfortunately the color balance was off even though the median RGB values seemed very similar, Had to fix that as well as do the final rotation in Photoshop.
