hey Martin

I think your idea of widefield must be different to mine!

This meteor shower pic was taken with a 24mm f1.4 lens on 5DmkII:
Geminid Meteor Shower

You *really* need fast lenses for meteors and I couldn't conceive of using anything longer than 50mm. There are very fast 24, 35 and 50mm prime lenses which is mainly where I would be looking. For a cropped sensor camera you 'could' consider the 10-22mm zoom but it's nowhere near as fast.

For widefield milky way scenes/landscapes I also use the 24mm (and my new-ish 14mm ultra wide).

For classic 'widefield' shots I have heavily used my 50mm lens. These two milky way mosaics are both three parts on a 40D with 50mm 1.4 lens:

Southern Cross

Centre of the Milky Way

For comparison, this is four part mosaic with 200mm f2.8 lens on 40D:

Antares, Rho Ophiuchi and the Blue Horsehead

And this is a single image with 200mm f2.8 lens on 5DmkII:

Large Magellenic Cloud

Hopefully that gives you some food for thought.

1. Milky Way, large asterism shots.

3. Meteorite showers.

So, I think about 100mm is good for Milky Way, but think that about 200mm is optimum for star trails.

100mm is probably too long for meteorite showers.

So, can 1 thru 3 be done with a single lens? Probably a zoom lens like 70-200mm would cut it?

any other thoughts?
