I am interested in your Northern Lights tour late September 2017 is there any chance of seeing the Lights.
We were there in early September and we could see them visibly with the naked eye on one night but not so much the next. It is all up to Mother Nature. We did take photos with our cameras and saw it in a different perception through the camera lens but you need a camera that you can leave the lens open at least 20 seconds. Good luck and enjoy. It is a beautiful sight. As I said earlier, all up to Mother Nature.
I had read much about it before I went there and I think that the following two sets of keywords will help you
The season goes from mid August to mid April each year. In late September you have good probabilities to see them; however, it depends on Mother Nature and in this sense it can't be guaranteed that you will see them 100% for sure. It is like saying you will see snowing one certain day in the Winter. Luck plays an important role! Additionally, Autumn is much less cold than the Winter and I heard that the colors of the trees is quite a spectacle worth to see.
When we visited in December, we saw them 2 out of 4 nights. There are no guarantees as to whether or not you see them.
Luck of the draw. Even the nights they weren't on show there were other things to do around a campfire.
Hope this helps.
