The Trifid Nebula (Messier 20)

Taken with the 14 inch and DS2.3+, the Trifid is a lovely sight. At f/5, the nebula fills the FOV of the imager. The Trifid is an H II region in Sagittarius. It is a combination emission, reflection, and dark nebulas, plus a star cluster. The dark lanes that define the lobes of the nebula are designated Barnard 85.
