Here are two photos of the Moon, five days apart,
showing the effect of libration , ie a little more of the western limb showing in the later image
This is due to the motion of the Moon in an eliptical orbit, as is the difference in size of the two images..

Technical details:
Camera: Olympus C2000Z at minimum optical zoom
Telescope: Celestron Ultima 8 f/10 with 30 mm eyepiece projection.
Date 2002 April 21 and 26
