Need some last minute help! Another Meteor shots thread!

Headed out in a few hours to catch the show. I'll be shooting from 145am to Sunrise.

I'll be bringing my 50d with a 17-55 2.8 IS and my Sigma 10mm 2.8 Fisheye

Sadly I have one body, and won't be able to shoot both simultaneously. I think I want to use my Fish Eye, and then straighten the image out. It will mostly come down to how I can frame the photo better.

I plan on shooting 23-30 sec exposures wide open, since either lens is rather sharp. The other option is to shoot at f8 or so for ultimate sharpness and to stack (which I don't have much experience with)

Wondering if stacking is surely the way to go. Also, which lens do you think I should use.

I would like to get results similar to this.

i don't much about this stuff, but it look like one was shot from an orbital position.

Maybe if you climbed up into a tree ... or went on the roof of the garage?
