You have many really nice shots there. As I looked through them, I was
trying to figure out why they looked so 'flat'. For the most part, it
looks like technically you are doing most everything right. Focus and
guiding look pretty good. I think you need to be taking longer
exposures, or stacking more shorter ones. 

Some really nice shots.
