Star Trails
Hi, I am looking at doing some star trails this evening and I was wondering what the minimum time the exposure would have to be to start to get a nice trail going. I am going to do a series of 30 second exposures and put them into star-Stax. I have done this 4 times before but I'm looking for the quickest possible time. Would 1 hour be good enough?
Regards Nick
