A busy sky – with a line of thunderstorms across the northern horizon, the circumpolar stars trailing above, a bright bolide meteor at left, and a bright Iridium satellite flare at right, all in the space of 2.5 minutes. I shot this from Writing-on-Stone Provincial Park, from near the Visitor Centre, looking north over the prairie. This is a stack of 5 exposures taken in sucession, each 30 seconds at f/2.8 with the 16-35mm lens and Canon 60Da at ISO 2000. These were frames from a time-lapse sequence.
