Spectroscopic verification of suspected planetary nebulae. I.
Abstract
Classification of eight objects as a planetary nebulae was confirmed according to the authors' image tube spectra. M4-1 is an emission line (Seyfert 2) galaxy, K2-13 is probably a plate fault, the status of He2-111 remains uncertain. Line identifications, estimates of line-strengths and mean radial velocities of all emission objects are given.
