On December 10, 2011 we had a total Lunar eclipse starting at about 4AM. A lunar eclipse is when Earth comes directly between the Sun and the Moon, so the Moon is in our shadow. Although it is much dimmer than the Moon is normally, it is still easily visible, being illuminated by light coming around Earth. The orange color is due to the refraction of light through Earth’s atmosphere. This is the same effect that makes the sky appear blue to us here on Earth.
Scope: AT111EDT at f/5.6
