Hi Jim,


If you wish, send me a link to the originals, I will fiddle with them and get you something back - no promises on quality.


I assume they were they captured using the same exposure settings?


Cheers,


Brian

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.
