Scientific paper

BV-1 is a Type I planetary nebula, highly enriched in nitrogen and helium with N/O = 1.5 and He/H = 0.17, powered by an exceeingly hot star. Imaging in: (1) [N II] (20% contamined by Hα) shows an elongated 54×32 arcsec (diameter) structure with a bright thin central bar and faint extensions, which the authors classify on Balick's system as middle-to-late butterfly; (2) [O III] shows a prominent dust lane; (3) the yellow continuum reveals no central star, and yields a lower (bright) limit to V(star) of 21.5. Kinematics, structure, distance, age and properties of the central star are discussed in detail.
