M20 - VC200L
M20 - Trifid Nebula
|
The Trifid Nebula (also known as
Messier 20 and NGC 6514) is an H II region located
in Sagittarius. The nebula's name means "divided
into three lobes". The object is a remarkable
collection of open cluster, emission nebula (the
lower, red portion), reflection nebula (the upper,
blue portion) and dark nebula (the septation
within the emission nebula causing the trifid
appearance, also designated Barnard 85).
Being a bright and colourful
object, the Trifid Nebula is a perennial favourite
of visual and imaging amateur astronomers using
telescopes of all sizes. The combination of star
cluster, emission nebula, reflection nebula, and
dark nebula makes it a beautiful deep sky object
and photographic target.
