Howdy
I see a lot of AP posts that mention the seeing being good or bad. How is this judged, is there a way to determine what it's like or will be like without actually spending an hour imaging? Is the standard method of imaging simply setting it up and hoping for the best, or can you look at a cloudless sky and somehow know there's not a lot of point in getting your rig set up? I've noticed that some cloudless nights the stars are amazingly clear and beautiful, other nights fairly dim - is seeing something you can easily judge by eye, or do you just have to spend the night shooting and see what you get?
I've been looking at SkippySky but I don't understand the differences between cloud cover, transparency and seeing...?
