Negative gray scale representation of an optical image of the Carina Nebula taken from the red Digitized Sky Survey plates, with superposed outline of the HAWK-I mosaic pattern. The individual HAWK-I mosaic fields are shown as boxes with a size of 7.5′ × 7.5′. The clusters Tr 14, Tr 15, Tr 16, Cr 232, Bo 11, and the Treasure Chest Cluster (TCC) are marked. The 2′ diameter blue circles mark the positions of the four embedded clusterings discussed in Sect. 6, and the six small red circles indicate the positions of the six Molecular Hydrogen Emission Objects discussed in 7.1. North is up and east to the left. A grid of J2000 coordinates is also shown.
