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.
