Scientific paper

The AAO/UKST Hα Survey has been used to discover a number of new, large, nearby planetary nebulae (PNe) These discoveries, combined with a critical re-analysis of all previously known large PNe, have allowed the compilation of a relatively complete census of PNe in the solar neighbourhood within 1.0 kpc. Distances are based in part on a new Hα surface brightness - radius relation. The census is relatively bias-free, and will provide more accurate estimates of the PN formation rate, average PN lifetime, and the total number of PNe in the Galaxy, as well as a first look at the faint end of the PN luminosity function (PNLF).
