Information that explained the Libration of the moon and it says that the maximum latitudinal libration of the moon is some 7 degrees 7 minutes lattitude. On the face of the moon, that is little more than the movement of 1/2 hour on a clockface. It goes nowhere near explaining an almost 45 degree movement of almost 3 + hours. According to the article on the Libration itself the maximum Latitudinal Libration would be 6 degrees and 50 minutes attributable to the tilt of the earth's plane of the ecliptic relative to the Lunar plane of the ecliptic and 50 minutes of Latitudinal Libration due to diurnal perspective during the moon's travel across the sky of the observer. This would result in a total Latitudinal Libration of a maximum of 7 degrees and 7 minutes, which, as I pointed out above accounts for only about 1/2 hour of what appears to be a nearly 3 hour shift in the latitudinal face of the landmarks on the surface of the moon.
