The Trifid Nebula (catalogued as Messier 20 or M20 and as NGC 6514) is an H II region located in Sagittarius. It was discovered by Charles Messier on June 5, 1764. Its name means 'divided into three lobes'. The object is an unusual combination of an open cluster of stars; an emission nebula (the upper, red portion), a reflection nebula (the lower, blue portion) and a dark nebula (the apparent 'gaps' within the emission nebula that cause the trifurcated appearance; these are also designated Barnard 85). Viewed through a small telescope, the Trifid Nebula is a bright and peculiar object, and is thus a perennial favorite of amateur astronomers.
The Trifid is located some 4100 light years away from Earth and is around 42 light years in diameter.
Telescope: 8" newtonian f/5 on EQ5 Pro
Camera: ZWO ASI178MC
Software: Sharpcap, DSS, Snapceed
Frames: 209 x 5 sec subs (Total - 17min 25sec), gain 190, offset - 0.
