This object sits just north of the Rosette Nebula, although it is half the distance away at 2,700 light years. The “Cone” shape comes from a dark absorption nebula in front of a faint emission nebula containing hydrogen ionized by S Monocerotis, the brightest star of the Christmas Tree Cluster above. This came out quite noisy even with a lot of subs, either the conditions have been poor or this is a pretty hard area to image in.
