Sextant, Eyepiece, Apollo 4
Apollo astronauts navigated from Earth orbit to the Moon and back in part by taking star sightings. The Command Module contained a sextant and a scanning telescope for this purpose. Sightings taken by the astronauts with these devices were translated into data that was processed by the on-board digital computer.
This sextant, made by the Kollsman Instrument Company, may have flown on Apollo 4, an unmanned test flight.
