@bfibbs Cities light pollution is also to blame. From the country you can see a large M31 naked eye but still way much fainter than Moon.
@rborba what I find it astonishing is not the luminosity, it's the spatial width.

@bfibbs And astonishing it is. M31 is 2 moons wide by six moons long, even though it's 62500000000000 times farther away!Thanks. Twitter will use this to make your timeline better. UndoUndo
