My first star-trail experiment......All the other stars "circling" the Pole Star a.k.a North Star or Polaris.
Shot atop Mt. Hamilton, California.... the only place I could think of in the SF Bay Area where the stars would look as bright as they have come out in this shot. Shot b/w 11.34pm to 12.58am. (118 shots at F/3.5, ISO1600, 30sec, stacked)
