A phrase I 've come across a lot on these forums is "the seeing was good" or poor or anything in between.
Now I understand what is meant by this in visual terms but I was wondering if one of you helpful people could explain what determines good/bad seeing?
What I mean is what makes the seeing good or bad. Obviously cloud cover, light pollution, dust & smoke make for bad seeing. What conditions would make for good seeing? High/low temperature, dry/humid, atmospheric pressure,winds or lack of, time of night or even year?
Are there any weather patterns to look out for(good or bad)?
As I've only been serious with Astronomy for about six months, I haven't been out on a clear crisp winters night yet,would the seeing be any better than in the warm Summer months?(note to self, get a nice warm beanie to cover my bald head
).
I hope my question isn't too stoopid but if I don't ask I won't find out
Cheers
