Blue Star Night
Nikon D90, 97 30 second exposures, f/4.5, 18mm, ISO 1000, Sodium Vapor WB (to make the sky blue).
Shot for NLP325's Blue Themed Week. I've taken a few very similar photos, but I needed a blue image for today, so I shot a star trail where I knew I could throw the sky blue with the WB settings. I wanted to have a star, then a trail, then a star, but evidently when I came outside to shoot the final star I moved the camera and things didn't line up correctly.
