field of view

(FOV, field of vision, field)
(angular measure of how much an optical instrument can view)

The field of view (field of vision, or just field) of an astronomical telescope is the angular area or solid angle indicating the amount of the sky the telescope can image at once. The field of view depends both upon the telescope and the instrument in use. Examples:

The term may occasionally be used to refer to the range of surveys, as both field of view and range indicate a portion of the sky covered.
