Subject: Help with solar mosaic

Seeing around Toronto has been pretty miserable of late, there were two nice Jupiter transits last week but the results were so poor that I didn't even bother processing the data, just deleted it right off the drive.

Saturday day was just as poor but I tried some solar imaging and even worse, attempted a solar mosaic because I had never tried it before.

The lack of stable surface features makes lining up the mosaic images very difficult and it got worse as I started building the solar structure up.  I ended up deleting the top 2/3rds but I'm still left with the uneven illumination of the various frames.  I don't know if its possible to process them out in PS.
