ic63 is an emission nebula in Cassiopeia close to, and associated with, the bright nearby star Gamma Cassiopeia. The star is emitting prodigous amounts of UV radiation and a strong solar wind, this is eroding the nearby molecular cloud forming the strange shape (I’ve called it the Dementor Nebula, maybe I watched too many Harry Potter movies ;-) ) This is a narrow-band composite of light in H-alpha, OxygenIII and SulphurII.
