Maz said:One of the landings was supposedly on The Sea of Tranquility. This is on the near side of the moon, so should be visible with a powerful enough telelscope.
In theory. In practise it's an average of about a quarter of a million miles away to resolve images that are very small and may not be lit up particularly well. If you work out the resolving power of say a 10m optical telescope or even the resolving power of something like the Keck at about 0.05 arc seconds it seems unlikely. The moon is only about 30 arc minutes across. If you apply this in a quick calculation (that may be wrong) the two telescopes combined don't stand a chance.
