\label{fig:1}  Optical image of the north end of the Orion A molecular cloud, including the somewhat more evolved populations of NGC 1981, NGC 1977, and NGC 1980 (Orion OB 1c subgroup) and the Orion nebula cluster (Orion OB 1d subgroup), projected against the Orion nebula (M42). This image illustrates well the complicated distribution of young stars in the vicinity of the ONC, with scattered groups of more evolved blue massive stars projected against partially embedded groups of younger stars (M43, ONC, OMC-2/3, L1641N).
