Sagittarius Triplet: In the Deep-Sky-Objects rich constellation of Sagittarius one finds a beautifull triangular arrangement of three outstanding emission nebulae, displayed in this image. Right of center is the famous Lagoon Nebula, extending downwards to the faint and not so well known Psychedelic Nebula (IC 4685). The third member of this triplet is the glorious Trifid Nebula at the top.

But there is more to see: Downwards to the left of Trifid Nebula one finds M21, a bright Messier Open Cluster and at the right edge of the image the Globular Cluster NGC 6544.
