Angular Resolution The angular resolution of a telescope indicates the sharpness of the telescope’s images. (a) This telescope view shows two sources of light whose angular separation is greater than the angular resolution. (b) The light sources have been moved together so that their angular separation is equal to the angular resolution. If the sources were moved any closer together, the telescope image would show them as a single source.
