North is to the top.
IC 59 & 63, the Ghosts
of Cassiopeia, are located about 600 light years from Earth. IC 59,
the "ghost" at the upper right, is classified as a reflection
nebula. IC 63, to the left and lower, is classified as an emission
nebula. However, it does show some blue reflection components. Their
main source of illumination is the nearby 2.15 magnitude star Gamma
Cassiopeia. |
