M20 & M8 - TSA102S
M20 & M8 - Trifid and Lagoon 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.

The Lagoon Nebula (also known as
Messier Object 8 (M8) and NGC 6523) is a giant
interstellar cloud, classified as an emission
nebula and H II region, in the constellation
Sagittarius. At an estimated distance of 4,100
light-years, the Lagoon is one of only two
star-forming nebulae faintly visible to the naked
eye from mid-northern latitudes. In binoculars,
the Lagoon is a distinct oval cloudlike patch with
a definite core, like a pale celestial flower. The
nebula has a fragile star cluster superimposed on
it, making this one of the leading celestial
sights of summer night skies.
In 2006 the first four
Herbig-Haro objects were detected in the hourglass
region of M8 also including HH 870. This provides
the first direct evidence of active star formation
by accretion in M8.

Just to let
everyone know, public viewing nights are held
every first Friday of the month. Clear or cloudy
nights the public viewing night goes ahead.
Members man a number of telescopes of various
sizes and types, and for those nights where the
