IC 59 and 63 are two separately-named pieces of what is basically one patch of nebulosity, lying very close to the bright star Gamma Cas in the upper right of the photo. The brightest part of the nebula is IC63; IC59 is the fainter and more bluish section at the right end. The OIII component in this nebula is very weak, but enough is there to produce the subtle blue colorations in IC59 and the tip of IC63.
This narrowband image was produced from H:O:S exposures of 2 : 1.5 : 1.5 hours, with O and S binned 2x2. 20 minutes of RGB was added to provide natural star colors.
