This three color composite made out of exposures in the B, V, and H-alpha filters represents more or less the naked eye sensitivity in the colors blue, green, and red, with an enhanced sensitivity in the H-alpha line.
This dwarf galaxy is a member of the Local Group of galaxies and has a distance of about 800 kpc (3 million lightyears). IC 10 lies in the galactic plane and all the bright stars in the image above are foreground stars belonging to the Milky Way.The morphology and absolute size of IC 10 is similar to our neighbour galaxy SMC (Small Magellanic Cloud). The diffuse yellow-green emission consists of a population of older stars. The red filaments which emit most of their light in the H-alpha line are HII regions with ongoing star formation.
