2) Picking your location:
You really can try this anywhere, but you'll find that if you're too close to town, then the 'light pollution' that emanates from civilisation makes it harder to see the stars, so rather than being nice and black, the background to your stars will become a pale haze instead, and this also means you won't be able to take as long a photo (ie such long trails) before it becomes completely washed out. The moon too adds significant light pollution so shooting during a 'new moon' (no moon) is ideal, or when the moon has set below the horizon, or at the very least, is well out of shot (and won't move in!). Of course you need a clear, cloudless night, and ideally a dry (not humid) night too, else condensation may form on your lens (some people literally wrap those little hand-warmers around the lens to keep it warm to prevent this). Also it's best to shoot from somewhere where there's less chance of a car, a torch-wielding person, or even a plane accidentally ruining your shot. Another point to consider when picking your location is what to have in your foreground. I think the best star trail shots are ones with something interesting framing up the foreground, so perhaps near some impressive trees and an old shed or something. Don't let all these ideals dissuade you though, you can still have fun and get some pretty cool shots in your backyard, in town.Star Trail For Mac
