Abstract
Spectroscopic observations have been carried out for eleven objects be lieved to be planetary nebulae on the basis of their optical appearanc e. They were discovered in an ongoing deep search for galaxies in the Southern Milky Way (Kraan-Korteweg & Woudt 1994). The objects were obs erved with the 1.9m telescope of the South African Astronomical Observ atory during our program for obtaining redshifts of obscured galaxies in the ''Zone of Avoidance''. Of the eleven objects, three proved too faint for a definite classification, four were galaxies with radial ve locities between v=3920 km/s and v=14758 km/s, but four were confirmed as planetary nebulae (PNE). Their relative line strengths and radial velocities have been determined. The PNE are on average fairly large ( 23 '' - 30 ''). Two of them (PN G298.3+06.7 and PN G323.6-04.5) were p reviously unknown; for these we show H alpha and [O III] images.
