Details:
What an amazing night this was. The sky was dancing with Northern Lights as soon as it got dark and the show continued all evening. I shot hundreds of frames for time-lapse movies. These are four frames, all taken with an 8mm fish-eye lens to take in most of the sky with the zenith point above centre. The orientation of the lens make the scene and resulting movie suitable for projection in a tilted-dome digital planetarium.
The Big Dipper is at left, and Orion is at right. Jupiter is below centre.
The location is the Churchill Northern Studies Centre on the shore of Hudson Bay in Manitoba, a location directly under the auroral oval. The temperature was -30° C with a brisk westerly wind.
The camera brings out the colours, which shifted from pale green and magenta at the start of the evening when the sky still had some twilight blue in it, to a deeper more intense green at the end of this sequence, lighting the snowy landscape green. Each exposure is 15 seconds at f/3.5 and ISO 3200.
