Consider an extremely powerful telescope.
Can it show a person standing on the moon from the side rather than directly overhead?

Right - I was trying to avoid all the libration discussion by using the words "somewhat stable" and "questionable communications." (Oh well...) E.g, near the limb, mountains can get in the way of line of sight to Earth.
The libration is small over short time scales, having a full period of a month. It is very pretty in fast motion, seen
here and
here.
NASA chose all the Apollo landing sites carefully so the Sun angle
helped them steer down and landing purposely occurred in an early quarter, so if they had to stay due to problems, sunset would still be days away.
