   My default setup is exposure of 60s every 61s. Star does not move quickly in the sky if you have a short focal length. However, if you leave gaps between 2 pictures, it will make wholes in the start trail, which are not great. This is a zoom of my previous star trail. Earth dash is the result of a 30s trail of a star, and the space between them is the result of 1s interruption to record the image and start the next exposure. Even 1s is enough to be clearly visible in the picture.
