Dry Spell? Reprocess old data!

Still working on fully assembling my new imaging rig and of course, the moon is back.  So, I decided to go back and reprocess my 1st light image from my Hyperstar almost 1 year ago.  This was M20 and M8 shot in Alt-Az mode as I didn't have a wedge at this point.  This image was completely unguided.  25 subs x 25 sec.  I didn't take flats or bias as I had zero experience with them at that point in the game since I had always owned small chip CCDs prior and there was no need for them.  Below is the reprocessed version versus the original pass.  You can see I was able to "flatten" it out and remove the vignetting with a few software tricks.
