I have a really nice (horrifying) image stack that one of my research team members made, that powerfully demonstrates what a huge problem satellite streaks are for wide-field imaging.

I have a really nice (horrifying) image stack that one of my research team members made, that powerfully demonstrates what a huge problem satellite streaks are for wide-field imaging. This is a 3 hour stack of star-subtracted 5 minute exposures using the Canada-France-Hawaii Telescope. The short diagonal lines are asteroids. The long diagonal lines are sunlit satellites that passed through the field of view during the exposure.

Paradoxically, an asteroid can hit the Earth by traveling hidden by the satellite streaks.
