The Hong Kong/AAO/Strasbourg H? planetary nebula database (HASH) [1] incorporates almost 300 true, probable and possible planetary nebulae (PNe) that have been identified since 2003 within the framework of the Deep Sky Hunters (DSH) project, and other amateur-based efforts [2-4]. Our sample covers all types of different PN morphologies, spectral properties, and evolutionary states. Estimated distances range from below 1kpc to extragalactic. This contribution focuses on all currently known medium- to large-sized PNe and candidates (optical diam > 2? ) in our sample.

The table below summarizes all 28 True (T) and Likely (L) PNe from the DSH sample with optical diameters > 2? and lists the fundamental properties of the nebular shells and the CSPNe. Previously unpublished objects are highlighted in blue. Statistically derived distances were taken from [5]. The listed CSPN magnitudes were extracted from PanStarrs photometry. For 15 objects with available UV, optical and IR photometry, we determined E(B-V) and T by fitting the spectral distributions of the CSPNe with distribution functions of blackbody emitters corrected for the effects of interstellar extinction using the formalism in [6] and assuming RV = 3.1. The GALEX UV fluxes were corrected by applying the revised photometric calibration from [7]. Effective wavelengths and zero points were taken from various resources. We note that two CSPNe (Pa 161 and Pa 153) have composite distribution functions with a hotter and a cooler component.
