Hi all, I'm looking for a way to calculate how much light is reflected from the surface, on the moon, and whether that light would be strong enough to be classed as a bright light source. I have no idea where to start with this, but basically I'm trying to prove a Lunar Hoax Conspiracy Crackpot wrong. He is stating that the Lunar Surface is not bright enough to obscure human vision on the moon so Astronauts can't immediately see stars. Obviously this is rubbish as Apollo astronauts have testified such, but ideally I need to prove it with some hard science. Any help would be appreciated.
