TLS image (left) and Spitzer-IRAC (right) showing the bipolar outflow from V1331 Cyg. The optical RGB image (left) is composed of I, Hα, and [SII] frames. The newly found HHOs I and J to the north are labelled according to the nomenclature of Mundt & Eislöffel (1998). The two brightest HHOs for which spectra were obtained are encircled in red. The blue circle marks an emission-line star without notable infrared excess. The 4.5 μm emission from shocked H₂ is marked by green circles in the IRAC image (right).
