Title: Narrow-Band Imagery and Spectroscopy of New Planetary Nebula Candidates at High Galactic Latitudes

Abstract: We propose a) a narrowband imaging campaign to verify the classification of 41 Galactic planetary nebula (PN) candidates discovered thus far on digitized sky surveys, following up an imaging and spectroscopy program started at KPNO, OHP, SAAO and UNAM. b) a spectroscopy campaign to confirm the nature of another 39 line emitters with H_(alpha) and [OIII] morphologies typical for PNe. The majority of the candidates are located outside of the Milky Way regions covered by recent narrow-band surveys (IPHAS and SHS) that are limited to low Galactic latitudes (|b| < 5^\circ and |b| < 10^\circ for candidates north and south of +2^\circ declination, respectively). Due to their large projected angle from the Galactic plane, many of the new candidates are likely to belong to the extended local volume (< 2kpc from the Sun). Thus, they allow a better extrapolation of the total number of PNe in our Galaxy, a metric that offers a critical test of the hypothesis that most planetary nebulae derive from binaries.
