Answer to Question 2

Closer to the equator will give you a view of more of the entire celestial sphere. The higher your location, the less turbulence you will experience, and less water to block the infrared. You want a large number of clear nights, very stable atmospheric conditions, and isolation from man-made light pollution. Such sites are often located on mountain tops in deserts, isolated coastal mountains in the Americas, and on mountaintops on islands like Hawaii and the Canary Islands.
