Thanks Paul, I guess that's why we're experimenting! On the topic of WA seeing however, it's not an opinion I formed in 5 minutes. The seeing in summer here is usually bad enough for the scintillation to be visible at zenith to the naked eye, and it definitely correlates with poorer views through the eyepiece.
The nights when the big girl really shines are when the temperature is plummeting towards zero, there's ice on the cars, and presumably no chance of the mirror being at equilibrium. The stars are steady, and I can crank the thing up past 800 power, no problem. If there's more to be gained by sorting out boundary layers on these nights, I'm all for it.
cheers,
Andrew.
