Interpolated images of M1-67 of the two observed regions: in the left column the edge pointing and in the right the central one. In each row we represent the flux (including continuum) integrated in a wavelength range. Top: range 5006 Å−5014 Å including [Oiii]λ5007 Å. Middle: range 6562 Å−6590 Å including Hα and [Nii]λ6584 Å. Bottom: range 6729 Å−6737 Å including [Sii]λλ6717, 6731 Å. All the maps are represented on logarithmic scales with units of log (erg cm^-2 s^-1). The size of the hexagon side is 38′′. In all the maps, north is up and east to the left (see Fig. 1).
