NGC 1553: Hα monochromatic map obtained from Fabry-Perot (Rampazzo et al. 2003) overplotted to the present Hα+[N II] contours. The Hα emission is clumpy and extends for about 30″. We note that the Hα peak is displaced from the Hα+[N II] centre and corresponds to the X-ray source Chandra CXOU J041610.5-554646.8.
