field of view

But the satellites are common enough these days that they often zip through the field of view of astronomers' telescopes, and their radio signals interfere with the signals used by those telescopes.

A telephoto lens offers higher resolution, while a wide-angle lens allows a larger field of view.

The director said that binoculars or a telescope are unnecessary and a potential hindrance because they narrow a stargazer’s field of view.

Given the telescope's field of view, that is about one chance in 10.

As satellites whiz past the field of view of telescopes, they leave streaks in the astronomers’ images.
