Among these objects:
- 10 have been confirmed as True PNe in HASH PN Database thanks their spectrum : PM 1-139, PBOZ 5, KLSS 1- 6, MPA J0639-0554, PM 1-20, IPHAS J192009.35+230816.6, IPHAS J191508.90+150951.5, StDr 1, StDr 30, SH2-123 (StDr 17)
- 2 were actually active galaxies showing noticeable redshifted emission lines (kn 134 and Hu 8)
- 1 was an emission line star (Mul IR-43)
