With data for >120 Galactic PNe, we present compilations of Ne, O, S, Cl, and Ar abundances. The impetus for this project is to probe the abundance patterns in our sample for enhancements and depletions of key elements that flag nucleosynthesis in intermediate mass stars. We point specifically to deviants from the well-established linear relationship between Ne and O as possible indicators of neon enrichment. These data are unique in that they are based upon spectrophotometry covering an extended range in wavelength λ3600-9600 Å. Utilizing ELSA, a 5-level atom abundance routine, we’ve carefully determined Te, Ne, ICFs, and total element abundances working toward a uniformly processed set of data. We gratefully acknowledge support from the AAS Small Research Grants program, NSF grant AST-0354056, and the Maria Mitchell Association.
