Here it is and it has been confirmed by one movie's sequence supervisors at Industrial Light & Magic and it is also confirmed it is the same guy that said this was just a space shuttle previously.
That's obviously R2-D2 out there in space floating through the debris field, that little guy gets everywhere. R2D2 is in fact in that shot, the Director figured out that our attention would of course, be on the giant cockroach of the spaceship, the Nerada. So people would completely ignore the little robot floating gently to the left of the screen. Ah bless.
Nice little easter egg and just in time in order to witness the destruction of Vulcan. A lot of people have said the chances are that the little guy was then sucked into the black hole and sent elsewhere, poor R2.
