Star and nighttime photography with my Olympus camera is so fun! Here is another attempt. The first shot is at 15s iso 320. Second is same amount of time but I flashed a red light on scene midway through.
For the star trails I used the Live Composite function. Set for same exposure, flashed light, and let it run for two hours. The moon was bright so I couldn’t run it longer than that. The first is the RAW file. The others are in camera ART edits.
