Lunar analemma -- moon pattern as it spins


Please click on image to expand. Yesterday we posted the Sun's analemma and today we were lucky  enough to fine a lunar analemma. Analemma happens because of the earth's tilt and it's oval-shaped orbit. It takes a year to complete the above photograph. As it needs to be taken everyday and then collated into one picture.
