Yellowstone

We went to Yellowstone park for a vacation. I took advantage of the dark skies to shoot some long exposure timelapse. Below is a test shot. In the crossed lines you can see the blinking lights from a jet flying East to West. The other solid line is the International Space Station. The white cloud in the background is the milky way.
