Apparatus and methods for finding and identifying objects in a nighttime sky include a lighted map arrangement (27, 28), an electronic compass (24), and means to operate (14-23) and view (25, 28, 31) the apparatus in the dark to either find the object in the nighttime sky or to identify (13) an object observed in the nighttime sky. The apparatus (24, 25) and methods provide for orientation as to the physical geographical location of the viewer and the current date and time (13, 19, 22, 23), as well as orientation of the viewing apparatus relative to the viewer and the nighttime sky (19, 22, 23).
