Wow, Russ, that's a cool animation!

You captured something I observed but didn't understand: How come when the Earth's shadow initially covered the moon, the shadow line seemed fuzzy and the moon was orange-toned, but when the Earth's shadow moved off of the moon the shadow line was very well defined and the moon was very bright white? Was it because it was later at night, and the sky behind was darker...?

There are different exposure lengths to compensate for the moon getting dimmer as it is eclipsed. Some are composites as well, to get both the dim red eclipsed part bright enough to see without blowing out the rest. Also, there are different processing and quality levels at work there.
