Nowadays is harder to shoot long integration times without getting any satellite passing trough the frame

Satellites, cosmic trash or UFOs, the moving spots are everywhere on the sky. Typical satellite behavior is to reflect sun light. It should be yellow or white and could fade and shine due to its rotation. At Saturday I was trying to make a stack of 50 frames of 30 seconds of Horse head nebula. I was surprised that during the 25 minutes integration I could count around 7 satellites passing trough the field of less then a degree. One of the objects was spinning very fast leaving a doted line on the frame. Below is a frame with 3 satellites passing at the same time in front of the horse head nebula. The lines are not straight due to the wind vibrations. I assume that those are satellites but in fact as I am not sure those objects are officially UFOs 😀
