This image is just an example, and it was shot near the city of St. George, Utah, so there is light pollution. See how to shoot star photos and night photography for tips on how to reduce this. This image was made from fifty 30-second exposure photographs. It took approximately 25 minutes to shoot all of these.

Optional Enhancements

Mask specific parts of the top layer and set it to normal blending mode if needed.
