False-colour image of the central Cygnus X region (left; Schneider et al. 2016a) and a zoom onto the region indicated by the red dashed box around Proplyd #7 (right). The R and G channels correspond to Spitzer 8 μm, while the B channel corresponds to Herschel (PACS 70 μm) emission. The proplyd-like objects detected by Wright et al. (2012) and Schneider et al. (2016a) are labelled in yellow (pr1-11). Proplyd #7 (pr 7) is located in the upper centre region, close to some massive stars of the Cyg OB2 association. These are marked in grey, following the nomenclature in Wright et al. (2015).
