So I have been taking night sky photos for a few years. Just as a hobby. Never seriously. Have only read some blogs and watched some videos and a lot of experimentation with the goal of just having fun. I know that star trails is yet another way to process those images but in all these years I had never once tried it. Just tried it on the images I took on New Year’s Day. These are 200 images (15s exposures) blended together to reveal the movement of the stars over an hour. The center of the apparent circle is the polar north, which is why all other stars appear to move around it.What do you think?
