Deep H₂ + continuum (2.122 μm) narrowband NOTCam image of the ≈4′ field observed in this multi-epoch study. N up, E left. Naming of jet structures according to the MHO Catalogue is sketched: MHO 2233 (magenta), MHO 2234 (blue), and MHO 2235 (green). The previously known HH 476 is labelled. Red circles show the positions of Class 0 and Class I protostars, the ID number according to designations by Enoch et al. (2009); for instance, 1 refers to the Class 0 source Ser-emb-1, which is named MMS3 in Djupvik et al. (2006). Only a few knots are identified with letters here, and the majority are identified in zoomed-in regions in the following figures.
