Okay, so in this question we're asked, why do astronomers build obstacle telescopes on top of mountains? and we are offered three options.
00:07
A, there is less light, there is less air to dim light.
00:10
A, less air to dim light.
00:17
B, we have the seeing is better.
00:26
And then ccds are charged couple devices.
00:31
Ccds work better with a beautiful mountain view.
00:35
Work better with a view.
00:36
So i think hopefully it should be clear.
00:39
That see will not be correct.
00:41
Work better with a view.
00:43
So we can discount that.
00:46
We can ask a question or what is seeing? so seeing is the quality of the view that the astronomers have.
00:59
Okay, so if the quality is better, the seeing is better...
