About this image

Waited for the moon to reduce and rise later in order to have enough dark time on this object. I did spend some time reducing the halo from Gamma Cas. leaving a little below to illustrate how it is shining on the two emission/reflection nebulae. IC59 (left) is closer to us (nearer than Gamma Cas) and IC63 (right) is further away (behind Gamma Cas). That geometry is what gives the more blue dust reflection on the left nebula and more red emission on the right nebula.
