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 ...

M 8 / NGC 6530
Size: 20' x 10' / 7' (Stoyan)
Distance: 4,300 light years (Stoyan)
Rating: **** (Stoyan).



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

My Own Observations

Observations Summer to Autumn 2016

Probably, I found M 8 with the Heritage 100P already at the end of August in Erkerode. At the beginning of September, I found it in Mühlhaunsen / Kraichgau again using the Skymax-102 on the GoTo mount. Actually, I only saw stars, maybe some faint glow in the Lagoon Nebula...
