North Star on the New River

So I had a very interesting Labor Day weekend trying to capture the North Star on the New River. The first night ended insanely cloudy and just couldn't get anything. Well the second night was PERFECT! I was about one hour into exposing and didn't notice the condensation on the lens. Well the last car that drove by made a GHOST like image on the shot and ruined it! Well after several hours of photoshop I was able to get something out of nothing. Here are the images and then the final. I had to reposition the sky a little due to the flare from the car and condensation. The bottom two were the ones I had to use to get the final.
