With several lunar charts being accessible online nowadays, including mobiles, here's one from the Lunar and Planetary Institute that took it way further, they have charts (for example from the LAC series), that allows one to scrutinize specific crater regions, famous ones like Plato, Copernicus, to name a few. Have fun with them! Perhaps one could even do it tonight with the big moon around!
