Problem I have with differential seeing tests is: it is too easy to confuse an momentary figure with say an RMS or average.

Planetary seeing (and imaging) looks at fleeting moments in the former, (in which case I'd claim similar numbers in Sydney) but the rub is: deep sky looks at the latter.

To be blunt, I'd suggest 0.7 arc sec seeing for deep sky simply isn't credible. (if it was, you have to question the professional ethic of putting domes on laminar flow covered high mountains)

But, if this is proven, I'd expect to see professional domes popping up like mushroom's at Clayton!
