The nebula is under the influence of ionizing ultraviolet radiation from hot,luminous star gamma Cas. Gamma Cas (magnitude 2.15) is physically located only 3 to 4 light-years from the nebulae and is just out of the field of view, to the south-west.This image comprises 5 x Ha, OIII and SII, all 300 seconds each, 0.5m f/2.9 ASA Astrograph with FLI ML3200 camera at an altitude of 55 degrees on 4 August 2017.
