IC 410 & NGC 1893 in Ha (11-25-09)

This is the most dramatic part of a nebulous area (IC 410) in central Auriga. Here as in the Pacman Nebula, the brilliant stars in the central cluster (NGC 1893) excite the surrounding hydrogen gas. The stellar winds from these bright stars are also pushing away the gas from around other stars, including those stars in the two tadpoles just down and to the left of the cluster.
