Telescope: Takahashi FSQ | Designation:The Lagoon Nebula (catalogued as Messier 8 or M8, NGC 6523, Sharpless 25, RCW 146, and Gum 72) is a giant interstellar cloud in the constellation Sagittarius. It is classified as an emission nebula and as an HII region. The Lagoon Nebula was discovered by Giovanni Hodierna before 1654 and is one of only two star-forming nebulae faintly visible to the eye from mid-northern latitudes. Seen with binoculars, it appears as a distinct oval cloudlike patch with a definite core. In the foreground is the open cluster NGC 6530. The Trifid Nebula (catalogued as Messier 20 or M20 and as NGC 6514) is an HII region also located in Sagittarius. It was discovered by Charles Messier on June 5, 1764 Its name means 'divided into three lobes'. The object is an unusual combination of an open cluster of stars; an emission nebula (the lower portion), a reflection nebula (the upper, portion) and a dark nebula (the apparent 'gaps' within the emission nebula that cause the trifurcated appearance; these are also designated Barnard 85). |
