Abstract. We summarize the results of narrow-band (H_alpha and [O III] 5007 Å) imaging of eight planetary nebulae taken during recent observing campaigns: We present the probably largest known PN, MWP 1, with a linear diameter of about 6 pc. We show first narrow-band images of He 2-437, MeWe 1-5, MeWe 1-8, MeWe 1-9, NGC 1360, and of - like we term them - the 'Galactic footballs' A 43 and NGC 7094.
We report about a search for planetary nebulae around eleven extremely hot (pre-) white dwarfs which had been not been successful.

Key words: planetary nebulae: general - planetary nebulae: individual: A 43 - planetary nebulae: individual: He 2-437 - planetary nebulae: individual: MWP 1 - planetary nebulae: individual: NGC 1360 - planetary nebulae: individual: NGC 7094
