Descripción
A planetary nebula has been discovered in the course of the INT/WFC
Photometric Hα Survey (IPHAS) of the northern galactic plane. It
is located near the galactic anticentre direction. Its small diameter
and low Hβ brightness point to an extremely large distance. The
``Shklovskii'' galactocentric distance of DGC = 14-->20 kpc3 makes
this nebula one of the farthest galactic PNe for which chemical
abundances have been measured.
