I was in my backyard taking pictures of the night sky. I was trying different shutter and exposure settings for a good picture of the stars. About 15 minutes in, I check the photo I had just taken and saw a large, foreign object. So I took another from the same position and caught what I would guess to be the tail end. I took more pictures but did not see it anymore. Further analysis of the picture reveals very clear white and red lights on an object in the sky.
