Captured this image of a piece of space junk. My guess is it's a flat surface that is tumbling and catching the sun on each rotation. Once I saw this I took another shot of the same area and it was gone. Notice between each bright point there is a much dimmer point. This tells me that the object has a reflective side and a much less reflective side.

A Satellite path cutting threw a galaxy. Slight tracking problem with this shot.
