Well, I have imaged with a KAF3200ME (6.8um pixels, 85% peak QE) at 3m FL (in pretty awefull urban skies) at an image scale of 0.47 arcsecs. And anecdotal evidence anyway was, that this level of oversampling was well worth it.
In one way in particular. Decon simply works better with more data. At times I upscaled at even this image scale and the result was even better.
Sometimes the capture math doesnt match the real actual picture aesthetics post processing. Anyway, thats my experience
