Abstract : The hand held sextant has several disadvantages in practical application. As it requires sufficient daylight illumination and weather clarity to see the stars and horizon simultaneously, observation of the altitude of stars is limited to short periods of dawn and twilight. The present invention overcomes the disadvantages and limitations of the prior art by providing a sextant having a low-level-tight television camera with remotely controllable sextant optics and a visual display. This invention includes a bidirectional gauge integral with and responsive to an apparatus for controlling the angular position of the sextant optics. The device is designed to provide a ship's navigator during both night and day the altitude and time of observation via a visual display such as a cathode ray tube or light emitting diode array along with the inforamtion of the celestial body being observed and the sea horizon on the cathode ray tube.
