On this page I collect my observations of the galactic emission nebula M 20, called Trifid Nebula, in the constellation Sagittarius.
The galactic emission nebula M 20 in the constellation Sagittarius is called Trifid Nebula because it consists of three parts. According to Stoyan, most observers are disappointed of this nebula when they see it for the first time, because even small light pollution can "extinct" the nebula.
Size: 15' x 10' (Stoyan)
Distance: 5,000 light years (Stoyan)
Rating: ** (Stoyan).
M 20 (nearly at the bottom) belongs to the constellation Sagittarius; the map marks further objects in Sagittarius that I tried to observe
