Reasonably faint emission nebula in Monoceros approximately 2.5 degrees from the Rosette Nebula. Located approximately 5,500 light-years away. Not imaged very often - it is not very exciting done with RGB filters. It shows up well using an Ha filter but requires a lot of time to bring out any OIII or SII signal.
