Night sky photography

This is my first time to take pictures of night sky photography.  It was much harder than I thought, but I had a lot of fun.  The starts look blurry in pictures because I was shooting them for 1 min exposure.  During the time, earth rotates and star moves, so you are seeing the movement of starts.  I gotta research of how to shoot stars, so that way I get crispy clear night sky pictures.

If you look at the last picture, you can see a line of light.  That is an air plane trail.
