Photograph o the full muin as viewed through a 9.25 inch Schmidt-Cassegrain telescope. This muin was near its greatest northren ecliptic latitude, so the soothren craters are especially prominent.

A full muin is the lunar phase that occurs when the Muin is completely illuminatit as seen frae the Yird. This occurs when the muin is in opposeetion tae the Sun (when it is on the opposite side o the Yird frae the Sun; mair precisely, when the ecliptic longitudes o the Sun an Moon differ bi 180 degrees).[1]
