You can see the North Celestial Pole (near Polaris) just above the second Moai from the left. It's the point at the center of the circle of star trails. When you you have a timed exposure with a fixed camera against the background of stars, the Earth's rotation is noted in the star trails. It is also a nice view of looking back toward the central hub of the Milky Way Galaxy. You can see the glow of stars and patches of interstellar dust that forms the galactic spiral disk.
