Stop spreading the myth that this will F up the night sky.
Your using hyperbolic language there, I did not say that.
The satellites are only visible at dawn and twilight because beyond that the satellites are well in the Earth's shadow and can't reflect sunlight.
And radio astronomy? Radar? Infra red? You need to learn a bit more about astronomy before you are qualified to comment.
Furthermore the positions of the satellites are known and predictable down to the millisecond in advance so any camera can briefly shut off the sensor for the instant a satellite passes its field of view).
The cameras used in astronomy are not your average cell phone camera and they literally do not work like that. It takes minutes to hours of continuous photon counting to produce one frame that will be one of thousands used in post processing to create a single image.
