IC 59 and IC 63 in Cassiopeia
IC 59 (left) and IC 63 (right) are two comet-shaped clouds near gamma Cas, the bright star in the upper left corner. The ultraviolet radiation of the star ionizes the atoms of these clouds, which emits light during recombination. Gamma Cas, IC 59 and IC 63 are estimated to be about 600 lightyears from earth in the constellation of Cassiopeia.
Long exposed RGB data was combined with Ha narrowband data. Considerable effort was required to reduce the brightness and reflections of gamma Cas (mag 2.15). North is at about 6 o’clock in this image.
