  We present Halpha+[NII] narrow-band imaging of FCC046 and FCC207, two dES in
the Fornax Cluster. B-R and B-I color-maps clearly show signs of
dust-absorption in FCC207. FCC046 has a very bright blue nucleus, offset by
about 1.1'' with respect to the outer isophotes. Moreover, FCC046 shows a
pronounced lopsided shape. The emitting regions differ considerably between the
two galaxies. Whereas FCC207 has only one central emission region, FCC046 also
contains fainter emission regions. Based on broad-band colours, its disturbed
shape and its very bright nucleus, FCC046 is akin to the class of amorphous
dwarfs. The central emission regions of both galaxies are resolved and we
estimate their diameters at about 60 pc. Their Halpha luminosities can be
explained as photo-ionisation by post-AGB stars in an old population. Some of
the emission regions in FCC046 are resolved and have diameters of the order of
50-150 pc and H$\alpha$ luminosities of the order of 10^30 W, comparable to
supernova remnants or nebulae around Wolf-Rayet stars. Hence, FCC046 is clearly
undergoing star-formation while for FCC207 the case is not as clearcut. We
estimate the mass of the HII gas in FCC046 at M(HII) = 40-150 Mo. The
ionised-gas content of FCC207 is somewhat higher : M(HII) = 60-190 Mo.
