Looks like you all get a treat with 3 posts today. This photo was an experiment I had done after learning how to use the interval timer on my camera for creating star trails. I think I got it down on how to do the process, but just need to find an interesting foreground now to do star trails. This one consisted of about 500-600 photos I believe. It is time consuming as you just set your camera and forget it. Let it go for as long as you want or until the battery dies.
