Cheers, George. The 2.5 tonne permanent pier 1.8 metres into rock makes fiddling with polar alignment a thing of the past for us, the dome prevents wind buffet up to about 60 KPH, the zenith sky is pretty black at Euchareena, and the 16803 has deep enough quantum wells except for really bright things like the Hourglass. We do sometimes use half-hour subs just so we get at least 3 subs in each channel on a single night - enough to do statistical data rejection.
