More than 150 objects from our
initial target list were imaged so far
during several observing campaigns
at SPM, KPNO, OHP and other
facilities using Hα and [O III]
narrowband filters. Of these, 106
were considered possible or likely
PNe, with a considerably high fraction
of spherical shells (≈ 20%).
Subsequent spectroscopic ob-
servations of 73 of the 106 objects
demonstrated that 64 are true PNe.
This gives a success rate of more than
60% for discovering a PN with our
technique, starting mostly from
available broadband data.

During the past decade, the Deep Sky Hunters (DSH) [1,6] and other pro-am collaborations [2] have
been searching for unidentified planetary nebulae (PNe) by scanning multicolour images of the
Digitized Sky Survey (DSS) and other publicly available digital resources (SDSS, GALEX, WISE), or by
inspecting [S II]/Hα/[O III] narrowband images of the Milky Way taken with modern CCD cameras.

Thus far, 210 PN candidates were identified in a region of ≈5000°. More than 80% of these were found
in fields complementary to those covered by the Hα surveys that were conducted recently at INT
(IPHAS [3]; |b| < 5°) and AAO/UKST (SHS [4]; |b| < 10°) for the northern and southern Galactic Plane
and that have led to the discovery of about half of the ≈3000 Galactic PNe that are known to date [5].
