We stopped here as part of our city tour. Great information about the lights but the best part was the tour guide actually showed us how to change our camera settings to capture the Northern Lights!
Glad to hear that you enjoyed your guided tour! Going through the exhibition on your own is great, but having one of our staff with you is certainly a key to a lot of additional info. (Including the camera setting- we are all happy to help there.)
I do hope you were able to catch some cool shots- don´t forget to share them with us if you do, we love seeing the results!
