Early Early Morning Autumn Star Trails.
With the continuing clear skies, I set up two cameras to record star trails early this morning. I started at 3:00 AM after the moon set. I was still worried about condensation on the lens. I pointed a Nikon D3 with a 16 mm f/2.8 fish-eye lens north, and a Nikon D3x with a 14-24 mm f/2.8 lens at 14 mm pointed south. I used some gaffer tape to prevent the focal length lens crepe on the 14-24 mm lens that ruined a previous star trails session. The Nikon D3 stopped recording after 2 hours. After the fact, I realized that I used a EN-EL4 rather than the higher capacity EN-EL4A battery. The D3x with a EN-EL4A battery ran until I went out to get the cameras at sunrise. Unfortunately, condensation on the lens started distorting images after about 5 AM. Both the North and South facing Star Trails ended up about 60 images (2 hours). The really bright trail in both the Norht and South image is Jupiter.
