Asteroid in just 1 frame?
Question in frame 4 upper right there's a sudden "star" that appears. I marked it as an asteroid, but really couldn't see the path. Any ideas what this is? Has anyone ever come across a nova?
it is likely just a single frame artifact. They can be caused by things like cosmic rays, but it is fairly common to have single frame artifacts like this. If it was an asteroid, it should be seen in all the frames unless it is moving into or out of the area right along an edge of a frame.
