I'm not sure whether this is good news or bad news, but you have your system operating at a level where the limit appears to be lateral charge diffusion.
Incidentally ... did you mask (the bright stars) for decon?

Hi Clive. I have been thinking about the need for finer sampling - it seems that my original design assumption of 2 arcsec as the best possible seeing was a bit pessimistic. Oh well, not a bad problem to have I guess. FWIW, the biggest gain in seeing came from putting the scope in a temperature controlled ROR observatory.
For this image, very little deconvolution was needed, since the original stack was about 2.2arcsec FWHM. I don't do any masking for deconvolution on the basis that the original convolution I am trying to wind back was a global process - and the PixInsight deconvolution process has effective clamping to minimise ringing on saturated stars. However, am open to alternative ideas.
