Haha it's hard to put words to what I'm thinking. So as the moon moves from west to east (talking proper motion against the background, not the motion you notice as the Earth rotates), it encounters the circular shadow of the earth. I was thinkin' it'd be interesting to rearrange the pictures to kind of portray the Earth's shadow in the sky, whereas this arrangement kind of shows up more as the shadow moving over the moon. Some other folks have been posting some interesting arrangement of eclipse pictures that got me to thinking is all.
