This is a cropped an reworked version of my data from 2019.
I used starnet++ v2 to lighten the nebula.
Object description (wikipedia.org):
The
Trifid Nebula (catalogued as
Messier 20 or
M20 and as
NGC 6514) is an
H II region in the north-west of
Sagittarius in a
star-forming region in the
Milky Way'sScutum-Centaurus Arm.
It was discovered by
Charles Messier on June 5, 1764. Its name means 'three-lobe'. The object is an unusual combination of an
open cluster of
stars, an
emission nebula (the relatively dense, reddish-pink portion), a
reflection nebula (the mainly
NNE blue portion), and a
dark nebula (the apparent 'gaps' in the former that cause the trifurcated appearance, 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 most massive star that has formed in this region is HD 164492A, an
O7.5III star with a mass more than 20 times the
mass of the Sun. This star is surrounded by a cluster of approximately 3100 young stars.
