Seeing and Transparency
What do you class as seeing vs transparency?
How do you rate them?
From my knowledge, seeing is the turbulence in the atmosphere, and is seen by the shimmering of the stars or of the moon/planets when viewing through the scope (or the twinkling of the stars naked eye).
Transparency, is that how clear you consider the sky? So if there's a lot of high cloud or haze or fog or something, then the transparency is poor?
How do you rate both of these?
