The Trifid Nebula (M20), with its pink (left) and blue (right) colours, is at the center. The Lagoon Nebula (M 8) is at its left. Very close to M20 is the open cluster M21, almost in the very center of the image. The faint nebula IC 4685 is also seen over M 8. The open cluster M23 is located at the bottom right corner (this cluster has a similar size to the full moon in the sky). The diffuse nebula IC 1283 is located at the top right, in the middle of a dark cloud.
