Overall morphology of a bipolar H II region and its environment. Pink highlights for the ionised gas, blue the molecular material, and grey shows PAH emission at 8.0 μm. Various sources are also represented. The two lobes are, in general, well traced at 8.0 μm; a wavelength band is dominated by the emission of PAHs located in the PDR surrounding the ionised gas. There is a dense filament, observed as a cold elongated high-column-density feature at the centre of the lobes. This structure appears in emission at Herschel-SPIRE wavelengths and in absorption at 8 and 24 μm.
