David,
It doesn't take very long to push a bright star to saturation. Often a few seconds is more than enough. I usually watch the star profiles on Maxim to pick a good exposure time.
Uneven illumination hasn't been a problem for me. The HDR process only takes the very brightest bits from the short exposure stack - just the star cores typically. The HDRComposition process has an option (on by default) that shows you the mask that was used. The short stack often looks pretty noisy and horrible but as long as the star cores are OK it doesn't matter.
Cheers,
Rick.
