DescriptionIC 59 and IC 63 (Sh2-185) - Gamma Cassiopeiae Nebula, L: 6x10min (1x1), RGB: 5x5min each (2x2), Imager Temp -20C. Despite their almost identical proximity to Gamma Cassiopeia and similar appearance, Sh2-185, or IC 59 (lower) and IC 63 (above and right) are actually quite different in their characteristics. Both are slowly being evaporated and dispersed into the interstellar medium by the nearby blue monster star.
Gamma is 40,000 times more luminous, 15,000 times more massive, and rotates at about 300km/hr, or 150 times more rapidly than our Sun.
