This is a four-panel mosaic of a large region in Monoceros that is mostly comprised of emission nebulosity harboring familiar winter objects (for the Northern Hemisphere) such as the Cone Nebula, Christmas Tree Cluster, and Rosette Nebula (place cursor over the image to see a rollover with labels).  Less famous but equally interesting targets in this vast expanse of gas include reflection nebulae, absorption nebulae, and star clusters.   More information about the Cone Nebula region and the Rosette Nebula may be found on Rob Gendler's webpage.
