C 59 and IC 63 are faint reflection and emission nebula located in the northern constellation of Cassiopeia. They are challenging objects to spot with telescopes for a number of reasons. Both nebulae are faint at apparent mag. +10, they have extremely low surface brightness and surround bright variable star gamma Cas (γ Cas). This remarkable star is partly unstable and is known as a “shell star”. It currently shines at mag. +2.15, making it the brightest star in Cassiopeia.
IC 59 and IC 63 are 610 light-years distant. From our perspective, IC 59 is located on the northern side of gamma Cas and IC 63 to the northeast. Spatially the nebulae are roughly 3 light-years from gamma Cas, although IC 63 is slightly closer to the star. As a result, it’s appears mostly red due to a dominance of H-alpha emission, whereas IC 59 exhibits much less H-alpha emission and appears mostly blue due to dust reflected starlight.
