Description
Ying focusing her telescope.
How to focus a telescope:
Identify a large object in the distance, without the telescope. Hold the telescope to the eye, and turn the focussing ring out as far as possible while looking at the object. Turn the focusing ring in the opposite direction slowly, to bring the object into focus.
