Default Would like to photograph the Perseids

I would like to take a long exposure of the night sky and capture some
Perseid meteor trails. If I turn my lens to its widest zoom, I have
a lowest possible f-number of 3.5; I assume that I want as wide an
aperture as possible. Meteors set their own exposure time, as it were;
so all that is left for me is to pick the ISO number. During long
exposures, I have a choice of ISOs running from 200 to 1600. I have
no idea how bright a meteor is compared to other things; should I
go for the highest ISO number and hope for the best? Or are they
bright enough I should choose a lower ISO and reduce both the noise
and the brightness of the surrounding sky?

Simplest thing to do is to take some test images and see if the sky
background is dark enough.
