After watching this month's lunar eclipse, amateur astronomerSebastien Gauthier carefully composed this montage oftelescopic images of th Moon sliding throughplanet Earth's shadow.While the deepest part of the total eclipse corresponds tothe central exposure, the play of light acros thelunar surface nicely demonstrates that the planet's shadow is notuniformly dark as it extends into space.In fact, lunar maria and montes arestill visible in the dimmed, reddened sunlight scattered intothe cone-shapedshadow region, or umbra, by Earth's atmosphere.For this eclipse, th Moon's trajectory took it North of theumbra's darker core, seen here cast over th Moon's crateredsouthern highlands.Gauthier's telescope and camera equipment were set up near theTrois-Rivieres Colleg Champlain Observatoryin Quebec, Canada.
