I am looking for a good 3 dimensional diagram of how the "precession of the equinoxes" is causing this Dec.21,2012 Galactic alignment with the center of the Milky Way,our Sun and the Earth.On a side note but related where does the seasonal tilting of the earths axis come into play with the" precessional wobble".in all of this alignment date.A good picture is "worth a thousand words".
Thank You.
