I captured the Ghost of Cassiopeia from my home observatory

IC 63 or the Ghost of Cassiopeia is an emission nebula in the constellation of Cassiopeia. Hydrogen that is being bombarded with ultraviolet radiation from the nearby star Gamma Cassiopeiae is causing it to glow. The nebula is part of a much larger nebulous region surrounding Gamma Cassiopeiae that measures approximately two degrees on the sky, roughly four times as wide as the full Moon.
