Faint Spiral Galaxy IC5332
IC 5332 is a very faint spiral galaxy 39 million light years away. It is a challenging target in light polluted skies. While processing the image I noticed several small galaxies around and in the background of its spiral arms. I'm interested in revisiting this target again with a longer focal length to see what detail I can tease from these.
