how does Earth's atmosphere affect what is seen through an optical telescope?
There is definitely visual turbulence that manifests in the view at the eyepiece. The view, especially at high magnifications, can appear as if there is a thin layer of rippling water between you and the object you are looking at. This 'seeing' fluctuates, and during the moments of still clarity, the view can be really excellent. These are the moments you wait for.
Different areas and climates have better local 'seeing' conditions based on the factors that influence this turbulence. The best views often come from areas of very low humidity, like deserts and mountain tops. That is why observatories are often located in these areas.
