The Lagoon Nebula
Object Type | Emission Nebula |
Constellation | Sagittarius |
Magnitude | 5.0 |
Size | 45.0' x 45.0' |
A large, bright emission nebula that is easily visible to the naked eye, M 8, also known as the "Lagoon Nebula" is a beautiful object in the telescope.
Visually, a bright cluster of stars (NGC 6523) dominates, with the nebula visible as a "fog" surrounding the stars. The prominent dark lane that gives the nebula it "Lagoon" title, is visible in a 4" telescope under dark skies. Unfortunately the red colour of the nebula is not visible to the eye.
40 minures exposures, Konica 3200 film.
6" f/3.75 schmidt-newtonian, prime focus.
In the centre of the above image is a very faint nebula surrounding a star. This is Sharpless 2-22. The star in the middle is the 7th magnitude SAO 185928.
45 minures exposure, Fuji Super HG II 400 film.
5" f/5 refractor, prime focus.
To the north (above) of M8 is the emission nebula, M20, also known as the Trifid Nebula. further to the north is the scattered open cluster, M 21. In between the Lagoon and Trifid nebulae are two faint emission nebulae. The one to the west is Sharpless 2-26 and the one to the east is NGC 6526. Also, there are nearly a dozen additional open clusters in the photograph.

To the east (lower right) of M 8 is a complex region of reflection and emission nebulae surrounding the 7.6 magnitude B0 star SAO 186366. This nebulae has several designations, including NGC 6559, IC 1274, IC 1275 and IC 4685. The yellowish cluster to the lower right of M 8, is the globular cluster NGC 6544
