The First image is the old Hudson Bay Whaling building the second is the old store, both in Apex just outside of Iqaluit Nunavut, which is on Baffin Island in the Arctic Circle. Not sure if Northern Lights fits in with the Long Exposure or Astrophotography but would love your feed back on these shots.
Both images shot at the same settings.
