Tricolour map of the 3″ × 3″ field around Th 28, combined from three emission lines outlining different emission regions: blue (Paβ), green ([Fe II] 1.644 μm), and red (H2 2.122 μm). The plane of H2-emitting gas is clearly orthogonal to the position of jet axis outlined by forbidden [Fe II]-emission. Three small squares give the position of the star calculated from the continuum stellar profile.
