Abstract

UWISH2 is the first unbiassed imaging survey of v$=1-0$~S(1) molecular hydrogen emission ($\lambda=2.122~\mu$m) in the northern Galactic Plane. Here we discuss 284 extended emission line objects which we consider to be candidate planetary or pre-planetary nebulae. Some are clearly associated with known PN, but the majority (60\%) have no previous detection. We have classified the objects according to morphology and find 53\% are bipolar with half of these being new detections. The remaining objects are mostly elliptical/round (35\%), fainter than the median sample flux ($4.4\times 10^{-17}$~W~m$^{-2}$) and previously undetected (74\%).
