Just had a play with the Drake equation Paul. Using some fairly conservative estimates for the unknowable parameters suggests that there may have been more than 1000 civilisations roughly like ours looking back this way from this bit of the sky when the light from Abell 2744 started out. Of course that was over 3 billion years ago, so they may not be there now

. Furthermore, when they looked this way, there were not even some photons from the sun to see, since light from the time of the solar system formation would not have got out there until relatively recently.
