I know that this is never going to happen, because those telescopes have much more important things to look for ...

But I was just wondering if we still did it, what would the best result look like? Would it look like

* a lighter pixel in a dark background
* those pictures of ISS taken in front of the Sun or the Moon
* could we get something a lot better than these, like a good resolution and being able to identify Starman as well

I am thinking about the best case scenario like best orbit position for Starman too
