IC59 & IC63 (Sh2-185) are a pair of emission and reflection nebulae that lie approximately 600 light-years away in the constellation Cassiopeia. IC69 (below and right of center) is sometimes called the "Ghost of Cassiopeia." The very bright star, Gamma Cassiopeia, illuminates these great clouds of gas and dust.
