Another Summer Nebulae combination (in the Northern Hemisphere), the Lagoon Nebula, M8 or NGC 6533, a bright Nebula (one of the few visible to the naked eye) in the constellation of Sagittarius and the Trifid Nebula, M20 or NGC 6514. The Lagoon Nebula lies 4100 ly distant and has an apparent magnitude of 4.6. A wonderful target to photograph, it contains much detail and many fine structures. The Trifid Nebula is a rather unusual target since it contains a hydrogen emission nebula component (red), a reflection nebula (blue) and a dark nebula.
This version of this wonderful region of the sky was captured on location at Hakos, Namibia. The bright colours are derived from narrowband Ha (red), SII (yellow) and OII (blue) data. The stars are acquired with RGB filters.
