The Cosmos with Barnard 344
Dark nebulae like Barnard 344 look much more interesting when silhouetted against such colorful clouds, the effect of the filters this imager used and the colors he assigned to them. B344 resides in the constellation Cygnus the Swan near the star Sadr (Gamma Cygni). (5.2-inch Thomas M.
