We have digitally co-added eight IIIa-J/GG395 UKST plates centred on the IC 4296 cluster of galaxies. The factor of increase in S/N in the co-added array enables galaxy profiles to be followed, and filamentary and diffuse features to be detected, down to bj surface brightnesses of 28 mag arcsec−2. Examples of warped disks, shells, trails, diffuse IGM and extended haloes revealed by this technique are discussed and illustrated.
