This a composite of 65 pictures, each 30 seconds long exposures
I have always wanted to take a picture of the stars using long exposure. I finally did that recently. Here is a composite of 65 pictures. You can see Stella Polaris (the northern star) in the center of the wheel. This is my first try, so this is not perfect.
Still, I find it quite interesting to note all the different colours of the stars.
