Star Trails, photo by Harold Davis. View this image larger.

I wanted to properly expose an image that showed long star trails without the moon. I set my timer to delay the exposure, which started at about 2:30AM and went on for 6,554 seconds (or close to 1 hour and 50 minutes) at f/5.6 and ISO 100. Besides the star trails, you can see fog on the ocean and the early light of pre-dawn.
