This night was a rare one. The weather was completely clear with no winds, the moon had set, and the temperature was even in the positives. Conditions were perfect for stargazing, and I had to take advantage of it. The dead silence in these grassy hills outside of Buffalo was only interrupted by the occasional howl of a coyote. I pointed my camera north and took pictures for 90 minutes, which I combined into this star trail image. It shows the stars apparent motion caused by the Earth's rotation. Each star in the northern sky takes 24 hours (23:56 to be precise) to make a complete revolution in a counterclockwise direction. The height of the North Star (also known as Polaris) is always equal to the latitude - 44° in this case. Any star less than 44° away from Polaris is circumpolar, which means it never goes below the horizon. The red at the bottom of the picture was a very dim appearance of the aurora. I couldn't see it with my eyes.
