Maybe that explains the artifacts?
It's actually got some awful green parts just under the galaxy.
However - I think everyone -including me - has become a little too fussy lately.
As for the colour debate:
Maybe we need to publish 2 results with every image i.e.
- one with fairly tame pastel colours & another boosted with LAB mode
in order to please everyone? 
cheers

Ah nah, it's all good, differing opinions is a healthy thing as long as we don't get too wound up and cranky (
)
As for Robbo's image and I'm not criticising juuuust observing
, there are tell tale signs of de convolution remaining on the stars, they are bright points inside more defuse discs and the background is evenly speckled, the gradients are pretty obvious too
I know the theory is probably sound but I always doubt the accuracy of deconvolution and how people apply it, how does the filter know to shrink a feature so that it remains the actual shape it should be rather than just get shrunk to a point with arbitrary or in fact differing shape and thus simply creating more of an
illusion of higher resolution...?There is also a magenta hue to the core area too..ok, ok sorry Rob not being critical it
was an APOD after all
