Little Streaks in the Sky

I took this picture over the Christmas holidays in Courtenay, up-island. Unfortunately, there was a power line going right across where I took the picture. I think the red color comes from a car that went by on the road. It was a little bit misty, and the lights just turned it all red. The exposure was almost 24 minutes long.

Just out of the picture to the top left is the north celestial pole, where all the stars appear to rotate around. Polaris, is near enough to the celestial pole that we see it as the north star, although it is a little bit off. Over the course of centuries and millennia, the north star moves as the earth precesses in its orbit. In just a thousand years, there will be no bright star near enough to the north celestial pole to call it the north star.
