Sorry but I still don't get it.
Take tonight for a good example. The sky is absolutely crystal clear (strange but true) so give it 10/10 transparency. It is beautiful up there tonight.
But it is not worth setting up as there is a strong wind howling through. So the seeing is about 1/10.
Is that correct.
If that is right then that goes against everything I have ever read in books and on the net.
I have only ever been taught (and read) about 1 method, and that method was called 'seeing' and it covered both scales. Tonight, on the scale I was taught, would be called approx 5/10 seeing.
