This is IC63 and IC59, taken over the course of 3 nights last week. IC59 and IC63 are Reflection and Emission Nebulae next to the bright star, Gamma Cas, which is the star right at the centre of the “W” in the constellation of Cassiopeia; around 550 lightyears away. Gamma Cas is an eruptive variable binary star, known as a "shell star"; it currently shines at mag. +2.15, making it the brightest star in Cassiopeia.
IC59 and IC63 are both around 3 lightyears from Gamma Cas. IC63 is slightly nearer and, as a result, it's appears mostly red due to a dominance of H-alpha emission from Gamma Cas. Because it is slightly further away, IC59 exhibits much less H-alpha emission and appears mostly blue due to reflected starlight.
Both nebulae are very faint, with extremely low surface brightness, and are easily washed out by the bright Gamma Cas (this is over 5 hours exposure on the Lights).
