The International Space Station (ISS) flies over Branch Lake in Ellsworth, Maine on July 25, 2017.
This was a really fun picture to take. My dad had been tracking the space station with a smartphone app, so we knew when it would be passing over the lake. The weather was almost perfect--a cool night, with clear air and few clouds--ideal conditions for taking long exposures. We trooped out to the dock after sunset and set up the tripod. I used an 11 mm lens to catch the wide-angle view. After a few test shots, we set the camera for a sequence of 30 second exposures and waited.
The station came over the lake exactly as predicted, and we started shooting. The resulting image is a composite of nine individual 30-second exposures, with the star-field rotated in each exposure to stack the light of the stars on top of each-other (compensating for the earth's rotation). We hope you enjoy!
