About this Image

IC59 and IC63 are very faint nebulae in Cassiopeia near Gamma Cassiopeia, the bright 2.5 magnitude star shown in the image above. IC63 is the triangular shaped nebula pointing to Gamma Cass and the arc-shaped nebula above is IC59. They are both highlighted and eroded by Gamma Cassiopeia, but IC59 is particularly interesting in that it shows both Hydrogen emission and considerable reflection nebulosity. These nebulae are 750 light years away.
