Messier 8 (M 8) - Lagoon Nebula

Introduction | Map | Sketch | My Own Observations | References

On this page I collect my observations of the galactic emission nebula M 8, called Lagoon Nebula, as well as of the embedded open star cluster NGC 6530 in the constellation Sagittarius.



According to Stoyan, the open star cluster NGC 6530 in constellation Sagittarius is actually the object that Messier described as M 8. Today, however, the galactic emission nebula NGC 6523, which Messier has described as a separate object, is regarded as M 8. Here, I follow Stoyan and describe both as M 8.

According to Stoyan, the Lagoon Nebula, being the brightest nebula, and the brightest open star cluster embedded in it "unite to the most awesome field in Sagittarius." Unfortunately, I was not able to see much of it. In France, I found, at least, the open star cluster...

Rating: **** (Stoyan).



M 8 (at the bottom) belongs to the constellation Sagittarius; the map marks further objects in Sagittarius that I tried to observe
