M - 20 Trifid Nebula
M-20 The Trifid Nebula. Only a short distance north of M-8, this object is rather easily found, but is considerably fainter than that object. A double star is seen surrounded by a mostly circular patch of light. This patch of light is divided into three separate regions by dark lanes which intersect near its center. On a good night, a fainter region of reflection nebulosity of almost equal size as the main portion can be seen to the north.
