A deep view into the area around the "Ghost of Cassiopeia"
IC 63 and IC 59
The "Ghost of Cassiopeia" describes two nebulae, IC 63 and IC 59, positioned near the star Gamma Cassiopeiae in the constellation Cassiopeia. These clouds of gas and dust are molded by Gamma Cassiopeiae’s powerful radiation; this star, located about 550 light-years from Earth, is known for its variable brightness. IC 63, the larger of the two, takes on a spectral, ghostly appearance and emits a red glow from hydrogen-alpha light stimulated by the star’s ultraviolet radiation. IC 59, on the other hand, is dimmer with a bluish tint, as it reflects Gamma Cassiopeiae’s light.
Once again, I wanted to use my fast f/2 optics and a 400mm focal length to capture not only RGB data but also as much H-alpha signal as possible across the entire region. My goal was to show how deeply IC 63 and IC 59 are embedded within the H-alpha clouds.
