2 Observations

The spectra have been obtained in April 1996 with the 2.5-m duPont Telescope at Las Campanas Observatory, Chile. Operating the modular spectrograph we covered the spectral range from 4800Å to 6800Å for all objects. Using the TEK1 CCD detector we obtained a spectral resolution of 2Å$\slash$pixel. The exposure time ranged from 600 to 1800 s. The raw data were calibrated using the standard stars LTT 3218 and 3864 from the lists of Hamuy et al. (1992 and 1994). The resulting spectra are presented in Figs.1 to 6. Additionally, narrow band images have been obtained for KeWe5 at ESO's 1.54m telescope and for KeWe2 and NeVe3-2 with LCO's 2.5-m duPont. The bandwidths were 62Å for (H$_{\alpha}$+[NII]), 35Å for [NII] and 57Å for [OIII].

The objects observed have all been discovered on ESO/SERC film copies during dedicated searches for PNe by visual inspection, for details of this method see Paper I.

Table 1 summarizes some basic data of the PNe.

 

Table 1:   Basic data for the PNe investigated

In the first column we give the common name (NeVe3 stands for Neckel & Vehrenberg 1990), in the second the designation following the IAU recommendations outlined in the Strasbourg-ESO Catalogue of Planetary Nebulae (Acker et al. 1992). Columns 3 and 4 give equatorial coordinates, measured from the ESO/SERC films given in Col. 6, accurate to about 6 arcsec. The coordinates have been measured using a high resolution digitizer and software developed at the institute. In Col. 5 a diameter is given as measured on the ESO-R film. Columns 7 and 8 give x and y positions on the ESO/SERC films or POSS prints measured from the lower left corner in mm of the field. G272.6-05.3 showed no emission lines but a continuum, therefore it probably is a galaxy.
