IC 63 (North Up, East Left)
IC 63 is an emission nebula in the constellation of Cassiopeia. It lies at a distance of ~600 light-years. 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. The fields of view of the two images are 34' by 23' and 18’ x 12’ and follow the CFHT convention, Ha-OIII-SII mapped to RGB.
