I think what one of the more frustrating aspects of the recent weather is the way that for some nights the sunsets look beautiful, the sky begins to take on that dark blue colour and even the brighter stars start to appear. The moment a piece of astro equipment appears outdoors the clouds rush in and covers everything. It has now got to the stage where I'm reluctant to set up the tripod for fear that the moment the scope is mounted the stars will vanish.
It would be worse if you go home and the sky will clear up
It was completely clear here all last night. Interesting that I had no telescope out though. Maybe there is something in that cloud-telescope law.
Maybe it does exist. What I know exactly - the observer-NLC law exists.
1. When you're observing (for many hours, with camera on the tripod, under the clear skies) - nothing appears;
2. When you're not expecting for NLCs - they always arrive;
3. When you are imaging NLCs - the camera batteries get empty.
(in this reason I always have another batteries with me)Here in Poltava the weather is perfect since Sunday (Jul.20). It is very hot (+30...+35C) in the daytime and very warm (comfortable +18...+23C) at night. Clear in the daytime, and
very clear at night. But the such beautiful weather will end tommorrow; rain is forecasted for the weekend.
