Thanks guys.
actually - what I am looking for is a lens that can do (in priority order)
1. Milky Way, large asterism shots.
2. star trails
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?
cheers
Martin
