It is connected to a hose in center from the Lunar Topographic Hyson camera. in the background is the ''mail box'', a jerry-rigged arrangement which the Apollo 13 astronauts built to use the Command Module lithium hydroxide canisters to purge carbon dioxide from the Lunar Module. Lithium hydroxide is used to scrub CO2 from the spacecraft's atmosphere. Original film magazine was labeled JJ, film type was Color SO 168, process ME4 on an Estar thin base.
