Details:
Composite images of lunar eclipses show us the Earth's shadow plus lunar features. Here the lunar features were removed from 80 minutes of data during the umbral lunar eclipse... only structure in the Earth's umbra shadow remains. The shadow is not simply circular, but shows features caused by changing refraction at the limb of the Earth. Since the moon moves more than a diameter during this time, all of the stars in the path of the eclipse are visible in this composite. The original data is monochromatic, so the color is approximated. A stray light halo surrounds the red shadow image, and the intensity from the original data was highly compressed to fit into an 8-bit image.
