Winter Sky over Mt. Humphreys

This is a long exposure (about 4 hours) of the night sky over the San Francisco Peaks. You'll notice the circular light path of some stars while one star doesn't move. The north star is almost perfectly straight above our north pole (which we spin along the axis of like a tire around a hub) so it doesn't really appear to move during the night. The other stars, however, will appear to move due to the earth's rotation. (They will appear to move, but it is really us, the earth, that is moving.) So, leaving the shutter open for long amounts of time will collectively gather light from the stars during the entire time the shutter is open, producing the rotating streak of the stars across the sky with the (mostly) unmoving north pole.

I don't normally brag about how difficult individual photos were to make, but this one is rather exceptional in what it required:
