NGC 2264 - Christmas Tree Cluster

Introduction | Map | My Own Observations | My Own Photos | References

On this page I collect my observations of the open star cluster NGC 2244, called Christmas Tree Cluster, in the constellation Monoceros/Unicorn.



The open star cluster NGC 2264 in the constellation Monoceros / Unicorn, is called Christmas Tree Cluster because it resembles a Christmas tree, depending on the observation instrument standing upright or upside down. The star cluster should be recognizable even with the naked eye. It also includes the Cone Nebula, a dark cloud.

Size: 20' (Stoyan)
