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

Abstract: We propose a narrowband imaging campaign to verify the classification of 45 Galactic planetary nebula candidates discovered thus far on digitized sky surveys, following up an imaging and spectroscopy program started at KPNO, OHP, SAAO and UNAM. 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 local volume (< 1kpc from the Sun). Thus, we will better estimate the total number of planetary nebulae in our Galaxy (extrapolated from the local volume), a metric that offers a critical test of the hypothesis that most planetary nebulae derive from binaries.
