Hi!
Great shots!
I'm astonished what you add (camera gear) to the already heavy several-day camping equipment for such a trip. I changed my gear to ultra-light backpacking, so that I can add a lot of camera gear, but only for overnight trips. Well, I'm already living in Norway with a nice scenery around.
You are using the Akto, right? I like the details (clothing on dry line), showing that it is from a real hike and not staged for photo purpose!
Did you took single-frame images or did you use e.g. multi-exposure with a longer exposure for the foreground (and probably a shorter for the tent if the lantern is too bright) which can be blend in easily?
I captured that aurora from 61 deg north with a bit of light pollution (Bortle 4) but easier access (1 hrs drive plus 20 min walk) and even there it was spectacular. I have had to use a 10mm lens on FF to get most of the display for a panorama. Pulsations and the corona were really great!
Winter is now slowly moving in with snow at higher elevation, making the access more challenging until it's suitable for skiing again.
