M72 - revisited

I imaged this object last year and thought it was the best I could do with my equipment and small size of the globular cluster (Link to post).  I was waiting for M30 to emerge so I decided see take some exposures of this object again.  Turned out to be a good decision as the old image looks embarrassing compared to the new image.  The only difference in equipment was the addition of 0.8 Focal reducer.  The other changes may be my improving processing skills and ISO at 1600 rather than 800. 

Even the sub-frames look better so it looks like the sky might have been better as well.  

Side Note: I got a couple of 1-minute exposures of M30 and that is all, therefore I will have to go offsite to image it.
