Bullseye!
It's a very striking APOD. Nevertheless, star trail images always drive me slightly crazy, because I want to identify individual star trails, and I can never do it.
Below the central tree in the APOD there appears to be two star clusters. Does anyone have an inkling as to what clusters they might be?
There aren't that many great clusters of reasonably bright stars not too far from Polaris. Forget the great globular of the north, M13, because it wouldn't show up as anything but an individual line in an image like this. I was thinking of Alpha Persei moving cluster, but I doubt it. How about Cassiopeia? Cassiopeia is a northern constellation, there are five bright stars there, and there are several clusters scattered among them adding more starshine to the scene.
