This image was made of 148 individual images shot as a timelapse sequence during sunset while camping above treeline in the Alaskan tundra in late summer. Slices of each image were laid next to each other, so that time increases as you go left-to-right. A flash was used on the foreground grass to keep them constant. You can see streams of wispy white passing through, which are noctilucent clouds, and the vertical green stripes in the upper right are the northern lights. #aurora #northernlights #noctilucent #noctilucentclouds #sky #timelapse #night #sunset
