There is a diffuse red nebula caused by H-alpha emissions from hydrogen gas stimulated by ultraviolet radiation emitted by S Monocertis and the cluster's other blue stars. There are two special star forming regions in the red nebula. At lower right, off the tip of the Christmas Tree, is the Cone Nebula, named for its apparent shape sculpted by fierce stellar winds emitted from the stars.
