FWHM ended up about 1.8arcsec after deconvolution, so it was fairly good. The difference in structure may well be just down to preference - I tried a (very) quick and (very) dirty selective enhancement on the posted jpeg and it extracted the same sort of structure as in the CTIO and Mike's image. Of course it also mashed the stars, but that can be managed - main thing is, the detail in the outer structure probably depends mainly on the aggressiveness of the processing and that is somewhat of a choice - maybe I should have pushed it harder.
