looks nice Paul - better than 1 arc sec peak to peak guiding noise is certainly good.
as others have pointed out, Australian seeing is definitely not up there with the best - I find that it doesn't normally get much better than about 2 arc sec where I am (sea level). If of any interest, data from Siding Springs and the Flinders Ranges (fairly close to Eric's system) shows that zenith seeing much below an arc sec is pretty hard to come by, even at elevated Australian sites. regards Ray
