We report the discovery of a small Hα nebula positionally coincident with the candidate neutron star AX J0851.9-4617.4 located at the center of the supernova remnant G 266.2-1.2. The nebula has a roughly circular shape with a diameter of ~6'' and a flux of ~10-2 photons cm-2 s-1 in the Hα line. Considering the uncertainties in the distance and energy output from the putative neutron star, we find that such a flux can be explained either in a bow-shock model or assuming that the nebular emission is due to photo-ionization and heating of the ambient gas.
