Description

This another of my series trying to do some imaging in my brightly-lit back yard using a 12 nm hydrogen-alpha filter. The Cresent nebula was formed by fast ejecta from the Wolf-Rayet star HD-192163. The farther-out nebulosity is probably from the days when the central star was a red giant, boiling off its outer shells.
