M8 Lagoon Nebula composite of twenty 10 second images at F3.3
Located in Constellation Sagittarius (the Archer), this emission Nebula is 45 arc minutes by 30 arc minutes, with a visual magnitude of 6. It is located 5,200 light years away, and is about 60 by 38 light years in size. Embedded inside the nebula is NGC 6530, an open cluster of 113 stars, with an overall magnitude of 4.6. The brightest star in the picture, to the left of the center, is labeled 9 Sagittarii, and provides most of the illumination for that part of the nebula. 9 Sagittarii is a hot O4 type star 23,000 times brighter than our own sun, even more than that in ultraviolet light!
