We can find out various diffused nebulae like broken clouds in the Milky Way in winter. Almost all of them had been discovered after the astrophotography was invented and developed. A diffused nebula I've displayed here is positioned in the constellation of Monoceros, has an expanse of 40 arc minutes or so at 2.5 degrees south of the Rosette nebula. The nebula can easily be taken in films only with a medium-ranged telephoto lens.
