Apollo 16 Lunar Module Flown Alignment Optical Telescope (AOT) Eyeguard from Commander John Young

It spent three days on the Lunar Surface on Apollo 16.

The alignment optical telescope is used for in-flight and lunar surface star sightings which are used as inputs to the guidance computer for determining the location of the Lunar Module in space.

Directly from John Young’s personal collection, certified and signed. The eyepiece carries the printed NASA numbers “6011834-011 KIC14 REV.B”. It is threaded on the inside, a further sign that it was used on the LM not the CM.

Part of the Future Ventures’ 🚀 Space Collection.

LM Stowage list, with this part number: Funny to see it listed along with the Lunar Rover and the Lunar Surface American Flag.Diagram of the AOT and eye guard location at the top of the Lunar Module:From NASA: "The AOT is a unity-power, periscope-type device with a 6 conical field-of-view. It is operated manually by the astronauts. Ten miniature red lamps mounted around the reticle prevent false star indications caused by imperfections in the reticle and illuminate the reticle pattern. Stars will appear white; reticle imperfections, red. Heaters prevent fogging of the mirror due to moisture and low temperatures during the mission"
