摘要

A planetary nebula has been discovered in the course of the INT/WFC Photometric Hα Survey (IPHAS) of the nothern 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 kpc makes this nebula one of the farthest galactic PNe for which chemical abundances have been measured.
