The paper presents a catalog of narrow-band images of 255 planetary nebulae (PNe) taken with the 3.5 m ESO NTT, using EFOSC2, the faint object camera, and spectrograph. The results include properties of several PNe which were previously listed as unresolved, show extended stellar objects, list several new bipolar proto-PNe, and describe a few previously unknown faint haloes. A new list is presented of sizes in H-alpha and forbidden OIII images, including information on all peculiar objects and features which have not been seen previously.
