2848 20160701171711.0 ASTROimport-1005 Exter, K. 2011 A HERSCHEL study of PNe This poster presents our on-going analysis of the PNe that have been observed so far with Herschel. These observations are part of the MESS Key Programme, which is looking at mass loss from evolved stars in the Galaxy. The PNe we present include NGC 6720, NGC 6853 and NGC 7293. The high spatial resolution of the PACS images allows almost direct comparison of the sub-mm dust to H2 images of the molecular gas, in particular for NGC 6720 and NGC 6853. The talk of Peter van Hoof will present the theoretical modeling NGC 6720; in this poster we include more detail on the reduction of Herschel data and present the latest PACS and SPIRE images for a closer inspection. We also discuss our future analysis, which will include a study of the spatial distribution of the material within the nebulae. van de Steene, G. van Hoof, P. Barlow, M. Sibthorpe, B. Ueta, T.
