Nice result Peter, I feel for you UKians must be very frustrating at times but then it's all relative...think of the guys who live at high altitude in northern Chile where over 80% of night sky time is useable across the year, sky brightness consistently around 22mag/squ arc sec and steady seeing at median FWHM values of around 0.7 arc sec prevail (meaning that visually through an 8" scope you wouldn't be able to detect any seeing issues
at all much of the year - I can't really imagine what that would be like.??) with best values hitting 0.2"
compared to them we
all live under a bright, regularly cloudy and violently moving soup
