Nice one George!
	It looks like you have got your hypering times figured out. There is
a bit of vignetting on the left and right sides of the image but nothing
major. For your next trick, have you considered an h-alpha filter? It will
allow you to get more detailed shots like:

http://www.astrofoto.ca/john/moonlight.htm  (tech pan)

Focusing can be tedious but I have a short write-up on how to get focus
nailed at http://www.astrofoto.ca/john/ha.htm . These filters also allow you
to shoot when the moon is up. Exposure times are long though!

I finally have a TP shot worth sharing.

At 18 minutes it could have done with more exposure and a little better
guiding.
Hope to re-shoot this week with slightly different framing.
