A large, long-term survey of southern hemisphere planetary nebulae is being undertaken with several narrow-band filters (primarily [N II], H-alpha, [O III] and He II) on the 0.9-m telescope at CTIO using a TI CCD chip. The purposes of this survey are to get sizes and morphological classifications for nebulae that are little-known (indeed, some do not have size measurements at all) and to search for multiple shells and other structures that are of interest for studies of nebular formation and evolution.
