Lunar Eclipses are caused be the moon entering earth’s main shadow called the “umbra.” When the moon is fully inside the umbra a total lunar eclipse occurs. The event shown below is a total lunar eclipse. When totality occurs, the moon usually turns a reddish hue, this is because the light passing through the earths atmosphere is refracted into the umbra and onto the moon. The blue light is absorbed by our atmosphere, and only the red survives and shines onto the moon.
All images where acquired with 110 FLT scope and ST4000XCM camera. Exposures ranged from .02s during the partial eclipse to 20s during total eclipse.
