I looked at the image again and I think DSS stacking might have "eaten" a few stars in the top corners, I've had it happen a few times and had to reduce the number of stacked images for the problem to go away.
The middle section is fantastic with nice bright detail!
Cheers,
Alex

In this case I exposed for 1 minute because I was having a condensatin nightmare so I had to wipe the lens often.
