Iceland Aurora December 2017

I was fortunate to be in Iceland over the Christmas period in December 2017, and as always in Iceland one of my favourite things to do is look out for the Northern lights.  Cloud was a problem but then on Boxing Day and for the following 3 nights the Aurora put on a good show.  Not the best i've seen, but certainly not the worst.  Temperatures of -10c on the night didn't make observing the aurora a pleasant experience but the view certainly helps to forget the cold.  All images were taken with the trusty Canon 350D, 30s exposure, ISO800 with the Sigma 10-20mm lens on 10mm f4.  A link to all images can be found in my Flickr below.
