Description
Important Lunar Module instrument used in LM/CM docking maneuvers.
Apollo 16 Lunar Module Flown Crewman Optical Alignment Sight (COAS) Directly from the Personal Collection of Mission Commander John Young, Certified and Signed. One of the most impressive and important pieces of precision lunar module-flown equipment we've handled. Its overall dimensions are 8.75" x 4.25" x 3" and it weighs more than 1.5 pounds. The Autonetics/ North American Rockwell metal plate attached has the information as follows: "SIGHT - OPTICAL ALIGNMENT - LM/ ME331-0018-0025", Part Number "41070-701-31", Serial Number "06359-0969 BKA", and Contract Number "NAS 9-150". Used on the Apollo 16 Lunar Module Orion that spent nearly three full days on the moon's surface. Suitable for the most advance space collections; these are seldom offered. Extremely fine condition with signs of moderate use.From NASA's 1968 "Apollo Lunar Module News Reference" comes a description of the construction and use of this Crewman Optical Alignment Sight: "The COAS provides the Commander with gross range cues and closing rate cues during the docking maneuver. The closing operation, from 150 feet to contact, is an ocular, kinesthetic coordination that requires control with minimal use of fuel and time. The COAS provides the Commander with a fixed line-of-sight attitude reference image, which appears to be the same distance away as the target. The COAS is a collimating instrument. It weighs approximately 1.5 pounds, is 8 inches long, and operates from a 28-volt d-c power source. [It] consists of a lamp with an intensity control, a reticle, a barrel-shaped housing and mounting track, and a combiner and power receptacle... The COAS is capped and secured to its mount above the left window (position No. 1). To use the COAS, it is moved from position No. 1 to its mount on the overhead docking window frame (position No. 2) and the panel switch is set from OFF to OVHD. The intensity control is turned clockwise until the reticle appears on the combiner glass; it is adjusted for required brightness."
Young has certified this item along the center tube: "LM flown Apollo 16/ John Young".
