:For this trick to work, the mirror would need to be placed AT LEAST two light years away and be at least 1AU big. Somehow I don't think this is worth it. Alternatively, you need more complicated optical system which would not only mirror Earth, but also create illusion it's further away. I still think such system would be more costly to build that ISS. Or ... well ... you could put an LCD display directly over the telescope. That's doable, cheap and as a bonus you can display planets from sci-fi there. -- [[User:Hkmaly|Hkmaly]] ([[User talk:Hkmaly|talk]]) 08:44, 28 June 2013 (UTC) | :For this trick to work, the mirror would need to be placed AT LEAST two light years away and be at least 1AU big.

::Under Hkmaly's initial proposal, the astronomer would have to make two observations, 4 years apart, in order to see the "other" telescope.
