OIII not as much fun

After the "easy" H-alpha shot I got with the mostly full moon, I thought this should have gone much smoother - better observing conditions, etc. But things did not cooperate. I took one set of 4 minute exposures on one night, but ended up throwing out too many and not getting as much data as I wanted. The second night I used 3 minutes and saved more. Since I noticed a rotation from my H-alpha shot, I tried to correct. Anyway, there is a total of 99 minutes. The focus/autoguiding on some of them wasn't what I had hoped, but I included everything that wasn't totally whacky.

So waddaya think - keep going for more data? Be more selective in what I add in? Just work on processing? Thanks for any suggestions.

OK, I hit post instead of choose file... It's still early.

Not much processing here. Just align and add. I fiddled with contrast and brightness.
