the satellites will be in Earth's shadow and not visible at all They'll still obscure any small/faint objects they transit. They aren't transparent.

- modeless 7y agoThey're not transparent, but they might as well be. They are small and very far away and most importantly moving at extremely high speed. I calculate that a satellite could obscure a small object of interest for at most a few microseconds. Considering that astronomy exposure times are often measured in minutes, this is absolutely a non-issue.
