I've been in the game for 40 years and I can almost categorically say that every time I've bought something new or wanted to observe, it's clouded over. If I just went out and observed, it'd be fine...planning seems to bring on the moist stuff!!!
Mind you, summer up here is a complete waste of time, so that means for around 7-8 months of the year, observing runs from blah to absolutely woeful to non existent. Winter is usually the best time here, but we still get clouded over every now and then, like today.
If I ever had the chance to get a CDK700 or something larger, I'd be accused of destroying astronomy in Australia because with my luck, we'd all have to move up to where you are...the rest of the country would've flooded from all the rain!!!!
I've learn't that if you ignore them and keep setting up then they seem to move on and settle in Canberra.
