NGC 2237/2244 (Rosette Nebula)

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

On this page I collect my observations of the galactic emission nebula NGC 2237 (2237-9/46) called Rosette Nebula and the open star cluster NGC 2244 in the constellation Monoceros/Unicorn.

 

Introduction

The open star cluster NGC 2244 is embedded in the Rosette Nebula NGC 2237-9/46. While the star cluster is bright and is said to be recognizable even with the naked eye, the nebula can only be seen if the sky is dark and, possibly, using a nebula filter. With the Vespera, I was able to see the nebula even without a filter; however, I had to take a mosaic to be able to capture the whole nebula.

March 2017

At the beginning of March 2017, I also looked out for the Rosette Nebula NGC 2237-39/46 (galactic emission nebula) in the constellation Monoceros/Unicorn using the Heritage P130 on my GoTo mount, but was not able to find the nebula, only the open cluster NGC 2244 inside the nebula, which was also not very impressive. Perhaps the narrow crescent of the moon already played a role in this... I assume that I saw the open star cluster (rather "nebulous") already when I "roamed" the respective area with binoculars (which is difficult to verify...). According to Karkoschka, this should be possible...
