Nebula rich region in the constellation of Monoceros, the Unicorn, with the dark Cone Nebula (left of centre) and the small V-shaped and bright Hubble's Variable Nebula at bottom, a reflection nebula that varies in form and brightness. Above the Cone Nebula is the triangular Christmas Tree Cluster, NGC 2264, here upside down as the bright blue star 15 Mon is the base of the tree. The large region of nebulosity is Sharpless 2-273. The V-shaped dark nebula above centre is LDN 1603. Near 15 Mon is a blue reflection nebula. Another blue reflection nebula IC 2169 and associated star cluster Collinder 95 is at left. Other bits of reflection nebulosity surround it - clockwise: NGC 2245, NGC 2247 and IC 446 above the main nebula. The rich faint cluster near centre is Trumpler 5.
