This is my first attempt at star trail photography. The photo was produced by stacking 48 one-minute exposures. It was a bit out of focus, I accidentally set the white balance on automatic, and I managed to bump the tripod partway through, but I still think it turned out well for a first attempt.
I also made a short time-lapse video from the photos used to create the star trail composite above. Shorter exposures (and more of them) would have made it smoother, but I still enjoy watching it.
