Details:
Using the photos I took of the Moon during the last total lunar eclipse, I've here made a composite image that demonstrates the size, colour, and darkness of the Earth's deep shadow (umbra) as projected into space at the distance of the Moon. There is a relatively sharp boundary to the umbra and a gradual decrease in brightness towards the centre. The red colour is due to sunlight from all simultaneous sunrises and sunsets shining through the silhouetted Earth's sky - satiating Selene with a sanguinary shade.
During a total lunar eclipse as seen from the Moon, Earth would appear as a dark circle with a bright red ring around it.
The umbra here is (very roughly) 2.5 times the size of the Moon.
