Thank your for this post, the map is amazing.

Unfortunately I live in a class 8-9 (5190µcd/m2) location right now, but recently I have been to a class 2 (6.41µcd/m2) location and in moonless nights the sky was indeed fantastic and incredibly immersive.

I have plans to move to the latter country in a few years time (for many reasons, but low population density and a lot of breathtaking nature/wilderness being among the top reasons).
