Galaxies are tiny little things in a telescope's view and a satellite always in that view, even if it's only one out of so many shots, could make it harder to glean useful data from an interaction between two galaxies like that. That beam is moving at near the speed of light and a telescope like this could tell us if there are fleeting but significant changes in all that power interacting with matter. Unless a satellite interferes with that light at just the wrong time.
