hi all
Here's the very first timelapse production from my nine weeks of photographic adventures in the Yukon:
The Venus and Jupiter Show, with special guests Aurora Borealis and the Moon:

This is less about the Yukon aurora and more about the conjunction between Venus and Jupiter which made a very nice evening sideshow during my time there.
This timelapse also features the two best sequences I captured with Fred (bassnut) Vanderhaven's automated twilight exposure control system. When it's working well we only need to touch the camera once during a sequence to twist the lens back onto the camera contacts to unlock the aperture and flick a switch on the control box at the same time.
The servo motors, external light meter and control system adjust ISO, aperture and Bulb exposure duration automatically taking care of everything else for the rest of the sequence. The temperature for the middle twilight to aurora sequence was -30C so it has worked in pretty extreme conditions although we did have some issues with severe cold at other times. As far as I know, there's nothing else like it.
