M1 is observable with even small telescopes, and is best observed around the new year. The Lagoon Nebula is a stellar nursery, a region of ionised hydrogen gas where stars are born. The nebula surrounds the cluster NGC6530, consisting of very hot young stars formed in the Lagoon Nebula. It is a bright magnitude 5.8 object, visible with binoculars, and covers an area of 90x40 arcmins in the constellation Sagittarius. But the best time to try to observe M8 is during July.
Photographs show much more detail and the contrast between the blue and red areas.
M20 can be found in Sagittarius. The Rosetta Nebula is a diffuse nebula surrounding the open cluster NGC2244. The nebula itself is very difficult to observe, but the central cluster is visible in binoculars. Look to the centre left of the Map . The best time to observe the Rosetta is during January and February.
