Very nice shot, but as jmark85 asked why so many shots rather than one long one. I recently shot some star trial shots and did long 10 to 20 min exposures. First time trying this and they turned out quit well. Will do 30 to 60 min next time.
From what I've heard, some digital cameras when shooting long exposures - the sensor heats up and causes spots to appear in the photo. Some call this "hot pixels". There is actually a post on here somewhere that shows a pic where this has happened. If I was on my computer, I would link this post for you. But because I'm posting via my iPhone, you'll just have to take my word for it...

I've been eager to try this. Looks like you have your technique down. Great improvement over the first!
Thanks!
