(meteorobs) advice needed to shoot meteors

[vaubaill]

Hi guys,

Here is a kinda unusual request. Here is the thing: I would like to
shoot some meteors with my digital SLR (canon rebel XT). I do not want a
too large FOV because in this case the tracks are so small they can
hardly be seen. So the focal length I am aiming to is around 50mm
EFFECTIVE, meaning a lens focal length around 35mm because of the
correction factor for digital SLR (1.6 for the Rebel XT).

Now I really need a FAST lens, since I'll shoot 5sec max., so forget
about anything slower than f/2.0

So you may think of the 35mm f/1.4 by canon, BUT for ~$1200, man that's
kinda a stretch for my wallet!

I saw the sigma 30mm f/1.4 for ~$400. Since I don't know wnything about
this brand, my question is to know if anybody here has ever tried this
one for astro-photography please?

Thanks for any advice ;-)

Jeremie
