Charlie:
I just took a bunch of shots of 15 minutes @ f4 @ ISO200 and they came out nicely. While I have a f1.4 lens, it doesn't stop vignetting until f4!!
Depending on your sky, I'd try 7 @ f4, 15 @ f4, 30 @ f4, the latter if your sky is pretty dark. If your at a darksky site, you could probably do an hour at f4 and get nice big stars.
I'm not entering in the competition, but here's a link to what I got http://home.att.net/~lee.suk/root/widefield/031004_Jupiter_in_Leo.html
It's a stack of a regular unfiltered shot, and another through stacked Cokin diffusion filters.
Cheers,
Suk
PS, take two each, I *always* manage to catch a plane...
