Star trails
The rings of light in this photo are called star trails. The stars, like the sun during the daytime, move from east to west across the sky every night. While you cannot see this movement with a naked eye, a camera set for long exposure captures the movement quite nicely. Each star creates an arc of light in a photo. The length of each arc depends on the exposure time (in case of this photo it was around 90 minutes). The star in the center is Polaris - since it always points north, it almost doesn't move, and its arc is barely visible.
What skill! Who would ever know slowing down your capture of God’s creation could possibly improve our view of Holy Creation!
I am in awe.
Thanks! Star trail photography is a very interesting area of photography 🙂 I hope I will find time to experiment with it more!
