"If we look a bit more closely, we spot the constellationof Pegasus with the planet Saturn (marked S1) clearly visible in the top left corner. Yet at the time of the mission, although Saturn appeared to be near Pegasus from Earth, from the Moon it would have appeared to be in a completely different position (marked S2).
It is almost insulting to think that NASA could get away with this obvious howler!"
So obvious! Why didn't anyone spot these sooner? Link
