I get 0.97 aspp with my QSI683 (5.4 micron pixels)/Paracorr (1.15 focal length multiplier)/SN10 (10" f4) combination.

Yes, arcseconds per pixel.
Criteria? Pretty much got them out of thin air
, but yes, I believe, perhaps naively, that sampling for galaxy imaging between 1" pp and above 0.6" pp should in a costal location yield comparable and optimally sampled data, as long as aperture will not limit the resolution and guiding will be spot on. Going below 0.6-0.7"pp for deep sky imaging in a typical coastal location in AU is a bit pointless, I presume
