Scientific paper

The major purpose of the investigation presented in this paper was to prove or disprove the nature of planetary nebula (PN) candidates in the southern hemisphere, selected from the third volume of the Atlas of Galactic Nebulae by Neckel & Vehrenberg. We present imaging and spectroscopic observations of seven PNe, five of them identified for the first time. An additional object probably is an H II region. All observed PNe represent evolved stages, their angular diameter ranging from 15" to 170", and exhibit low surface brightnesses.
