I shot this using a little point-and-shoot (Canon SX200IS). It is not the best low light performer, but the CHDK firmware allowed me to open the shutter indefinitely and shoot in raw (http://chdk.wikia.com/wiki/CHDK). The preloaded firmware does not allow this. Also, to ensure my finger did not jostle the camera when I pushed the shutter, I set the shutter timer for three seconds. The camera was sitting on a tiny tripod (http://joby.com/gorillapod/micro250). Shooting in raw made all the difference – the jpgs look really underexposed but the raw images retained all of the low light data. I was able to get some decent images by simply increasing the exposure value in post-processing.
Not the best images of the aurora – it was really windy too – but I think it’s cool that an old point-and-shoot could make decent images.
