Sh 2-185 is an H II region centered on the massive star system Gamma Cassiopeiae in the northern constellation of Cassiopeia. The region is surrounded by a dust shell and includes the reflection and emission nebulae IC 59 and IC 63.[2]

IC 63 is sometimes dubbed the Ghost Nebula, or the ghost of cassiopeia.[3]
