If I have a 7.4μm pixel camera mounted in an 800mm / f/8 refractor, with usual seeing of around 3 arc sec, I should achieve around 1.9 arc sec per pixel, which theoretically SHOULD be borderline undersampled (assuming rule of thumb of half seeing)
If I then run it reduced by 0.7x, this seems to make it slightly OVERSAMPLED.
So, which is the better position to be in? Run it reduced (larger FOV, faster, slightly oversampled), or native (smaller FOV, slower, slightly undersampled).
I just don't want darned blocky stars
(I really regret selling my KAF8300 now... oy vey!)
