The major purpose of this paper is to investigate the
nature of planetary nebulae (PNe) candidates in the southern hemisphere,
taken from an internal list. We present spectroscopic observations and
imaging of six PNe identified for the first time.
Another candidate turned out to be a galaxy. All observed PNe
represent evolved stages, their angular
diameter ranging from 15 to 120
, and exhibit very low
surface brightnesses. For three PNe indications of interaction with
the interstellar medium (ISM) has been discovered.
Key words: surveys -- planetary nebulae: general
