Images of BHR22 = CG13. From left to right: optical, 3.6, 4.5, 5.8 and 8.0 μm. Optical images are digitized photographic plate portions, hence not absolutely calibrated and no color bar is given. They only help to identify the objects. Infrared image scales (MJy sr^-1) are adjusted to maximize the contrast. Coordinates are identical in all five boxes but shown only in the first box. Type of cloud: PAH emission (or BRC, see text), presence of an IRAS object.
