Seeing
I was out with the scope last night after a couple of weeks of fairly poor weather and was a little surprised to find the seeing was pretty poor, despite the evening being fairly still and not a spot of cloud all day. My 6 mm was useless, whereas the other day when there had been high haze all day and wind, it was better than I expected.
Presumably, air movement in the upper atmosphere has more effect than down here in the troposphere. I've seen links to satellite maps of the jetstream before, could someone repost here and more importantly, tell me what I'm actually looking for in those maps.
