Thanks... I know it still needs some tweaking, but I think I may be starting to grasp the basics, which is the most important part.
I noticed also that with the shorter exposure times the stars don't look as bloated, and it seems that there is decent data there to work with.

You can always use the "Deconvolution" tool in Pix too. Lower the top slider (StdDev) from default of 2 to 1.5 and hit apply button. You'll see a change on the star in the preview window. It can/will correct elongated stars too.
