Thanks, Phil.
I used Austostar Envisage (free software from Meade) to stack this, but since then I found out that Deep Sky Stacker does a better job of de-rotating and averaging the exposures. I found that 15 second exposures at 14mm focal length work best with Deep Sky Stacker and it can successfully align 7-9 images, which is enough.
Strictly speaking Nikon D700 does not need much improvement on a 30-second exposure at f/2.8 and ISO 3200. It would be hard to tell the difference in a print unless it is very large. In all of my other photos at
http://www.terrastro.com the sky is not stacked.
Cheers,
Alex
