Descripción
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 15arcsec to 120arcsec , and exhibit very low
surface brightnesses. For three PNe indications of interaction with the
interstellar medium (ISM) has been discovered.
