Star Trails

[saltface]

These are just a few shots I took out camping. It's funny how you don't mind getting up at three to start a new shot. Must be the excitement at possibly getting a good shot.

I know these aren't the best compositions, but they're the best I had available. Any suggestions on post processing?

This is how.

I'd really recommend hitting the pawn shops for an old full manual film camera if you want to do this on a budget.
I've heard of people using generators for external power on DSLRs. Otherwise, a three hour exposure, such as the last one (well, actually 2.6716 based on the arc length) will definitely kill a battery. You'll also want to cool a DSLR to reduce noise.

I really like #3. It has the crispest focus, least light polution, and a bonus of the small meteor and the plane trail in it...very nice.:thumbup:

Funny, I always hate the plane trails.
Focus can be touchy on these pictures as post process noise reduction can make everything a little blurry.
