Notes   This image encompasses three Messier objects. In addition to the Lagoon Nebula (M8) and the Trifid Nebula (M20) we also have the open cluster M21 in the left hand corner. The core of M8 is a powerful star formation region. Stellar winds from the bright core star Herschel 36 are responsible for carving out the dark lanes. Another hallmark feature of the Trifid is the juxtoposition of the red emission nebula with the blue reflection nebula regions.
