Upper left panel: a MUSE image of NGC 7796-DW1 showing the three different nuclear regions with a square root scaling. Indicated is the mean flux in the interval 4800 Å–5550 Å. As in the other maps, the unit is 10⁻²⁰ erg s⁻¹ cm⁻² Å. Upper right panel: a map of the Hα-flux. The Hα-emission defines an almost complete, but distorted ring with some swellings and knots. Lower left panel: [OIII]5007 map. The [OIII]5007/Hα ratio is constant which indicates local ionising sources. Lower right panel: [NII]6583-map.
