This is a wide field image captured around the Rosette Nebula floating in the dimmed Milky Way of Monoceros. One is likely to take an attention to only the Rosette Nebula, but we can detect very faint nebulosities in wider field.
The dimmed and vast reddish region in upper part of this picture is an inter-stellar gaseous matter surrounding an open cluster of NGC2264 that contains a variable of S Mon. And the pale nebula and Rosette Nebula are linked with a moreover slight reddish nebula like a swirling gaseous flow. Those nebulae cannot be detected with our naked eyes at all, and it might be needed very high transparency and dark night skies to record those nebulae on digital devices.
This picture contains several other diffused nebulae bathed in the winter's Milky Way; you can browse individual images from anchors below.
