(via APOD: 2011 November 3 - IC 59 and IC 63 in Cassiopeia)
Gamma Cas, a powerful star in the constellation Cassiopeia, the Queen, is just off the upper right of this image, and is providing the ultraviolet radiation that is ionizing these two gas and dust clouds and blowing them away. IC 63, to the right, is the object I fiddled with astronomical data from the ESO’s DSS/DSS-2 to try to create a composite image for. It is closer to the star and is showing a lot of red hydrogen-alpha light. IC 59, to the left, shows more blue because it is dust reflecting the starlight that is most prominent in the nebula.
Someday, I’ll be able to make imagery like this from FITS data. Someday.
