Replying to How to photograph the Parseids?

So I'm going out tonight at around 3am to shoot the parseids. I was thinking of using ISO 1600, 30 second exposures and a 3.5 aperture (That's my widest). Then just using an intervalometer to get as many shots as I can. Then compiling them all in photoshop to get a cool looking shot, maybe time lapsing as well.. Would these settings be good? I'm not sure if I should go with a shorter exposure or anything, suggestions will be appreciated! I have a 60d by the way, so anything above iso 1600 will be pretty noisy. Gavinrudy I know you have answers for this.

(Yes, I posted this in M&A, I just want some more responses since I want to get this right)
