ABSTRACT:
A conformal identification apparatus is disclosed. The apparatus presents to an observer through an aided eye at least first and second representational objects corresponding to first and second actual objects. The apparatus includes a map that contains the first and second representational objects; a magnifier disposed between the map and the aided eye that presents a magnified image of a portion of the map including the first and second representational objects; and a support structure that supports the map and the magnifier. The apparatus enables the observer to view the first and second actual objects through an unaided eye simultaneously with viewing the magnified image with the aided eye. The magnifier has a focal plane and has a magnification determined so that, when the map is positioned approximately at the focal plane, an angle observable by the aided eye between the first and second representational objects is approximately the same as an angle observable by the unaided eye between the first and second actual objects. The map may be celestial and the apparatus may be used to identify stars, constellations, and other celestial objects.
