My friend and I went to this remote train tressel to shoot star trails because it is one of the darkest places in our area. After setting up and starting the series of shots a train came by that we did not expect. I thought it would ruin a few of the shots that I would have to take out and leave a blank spot in the trails but when I got home and put them together I was quite surprised.
