Caldwell 49 - The Rosette Nebula


5,000 light years away, the Rosette Nebula is striking in both narrowband and here in visible light (where it is primarily red in color). Because of its large size, only small magnification is necessary to capture the nebula and visually, the central cluster is easy to see. The central area houses cluster NGC2244 and NGC2237; the bright cluster of hot, young stars illuminates the gas of the nebula.
