living in a valley screwing me?
Posted 25 February 2013 - 08:30 PM
Ive been wandering if living in a valley is ruining me "seeing" more often than not. It seems on nights predicted 5 of 5 for transparency Iam still limited to low magnifications.
Couldn't I be in a different temp of air being in a valley with turbulence/different temperature at the mountain tops?

So observing is like viewing from the bottom of a waterfall.
Twinkle, twinkle little star is more than a children's song.
That said location does make some difference even within our small valley. Moving six miles did improve my seeing somewhat. My cabin at 3000 and 10 miles away does have much better seeing.
I did not think that the east would have that much variation given the lack of elevation relief.

We are too up on the mountains, why should the valley be any different? Really doesn't matter where you live.....
Valleys are profoundly different from mountain slopes because they collect cold air. Location makes a huge difference; even moving a few hundred feet can sometimes make a major difference in seeing.

So conditions can be as local as that to make a diference.
If I get a cold southerly blowing from down the Antartic way sometimes we get crystal skies with mag 7 seeing.
And I am only 5 miles or so from the CBD ...!
