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. Three reddish nebulae this picture shows you are positioned in Monoceros, paralleling from northwest to southeast at just south of the Rosette Nebula.
A diffused nebula of Sh2-280 at upper right-hand side has a span of 40 arc minutes at 2.5 degrees south of the Rosette nebula.
Sh2-282 in center is the dense one in three, floating around the center of Wintry Great Triangle. The nebula has a size of 30×10 arc minutes in N-S and E-W directions respectively.
Lastly, a dimmed nebula in lower left-hand side is Sh2-284. The nebula has a size of about 20 arc minutes, and is surrounded by dimmed reddish gaseous matters.
