Hehe, I finally got the original site to load (very slow) and it's got more information. It has agraph of the planet positions and my diagram is almost exactly right. (Yay me.
) But I still can't figure the apparent (to me anyway) size difference. The site says the images were taken seperatly and mosaized together. I wonder if the two planetary images are at different magnifications? It doesn't say they are, but that would explain it.
