  What it is

IC10 is classified as a dwarf irregular galaxy. It is also referred to as a starburst galaxy and is the most active star formation galaxy in the group. Compared to the Small Magellanic Cloud (SMC), IC10 has a larger number of Wolf-Rayet stars. IC10 lies near the galactic plane of the Milky Way and due to interstellar matter exhibits a reddening hue. The yellow and green emissions are from older stars. The red filaments are H-alpha regions with active star formations.
To bring out the starburst regions more effectively the color frames would need to be at least doubled from those used in this final image.
