"a bright visitor passing through the inner Solar System. Now, the orbiting satellites themselves only appear as streaks because of the long camera exposure, over 10 minutes in this case. On the contrary, to the eye, satellites appear as points that drift slowly across the night sky and shine by reflecting sunlight -- primarily just after sunset and before sunrise. The featured image was taken just before sunrise two weeks ago from Bavaria, Germany."
I guess the only ways to access the natural sky is to leave the atmosphere or to use AI to remove the trails.
They aren't blinking. The apparent blinks are due to intermittent, rather than continuous exposure. The gaps you're seeing are where the satellites were when the camera wasn't capturing.
What's really happening here is that they've used a post processing method specifically designed to highlight the satellites rather than the comet. This method would have rejected the satellites.
