Not sure what their general seeing conditions are like (couldn't see it referenced anywhere?) but I an sure it is better than any of ours....I'd just like to have so much clear sky that I could manage to collect 115hrs of
usable 
exposure, in just two months.....and that may not have been the only object being imaged over that time either?!
The three images they have released so far are to me superb in every aspect.
