A dust ring surrounds the central starburst region in M 82, resulting in strong additional reddening of light emerging near the equator. The starburst is contained in a flattened, optically thick region inside this ring. The concentration of scattered light near the minor axis is explained as the combined action of the cos ϑ-emission-law of the flat source and the shadowing by the ring. The dust ring may be spatially coincident with the CO-ring.
