A Zeiss camera lens carried on to the lunar surface during the 1971 Apollo 15 mission has sold for $370,026.
The lot crossed the block at RR Auction on April 21.
Astronaut Dave Scott used it to take around 300 photographs, some of which are among the most iconic images captured during the Apollo era.
Apollo 15 was hugely successful, with astronauts spending three days on the surface of the Moon - the longest time to date.
The lot is accompanied by a letter of provenance from Scott that reads: "After our three days on the Moon, [the lens] was returned to the Command Module in lunar orbit where it was used for two more days to photograph the surface of the Moon.
"After the mission, I received the lens from NASA as a memento of the mission and it has been in my personal collection since that time."
The range of space memorabilia coming up for auction has increased dramatically in recent years, following a 2012 relaxation of laws preventing astronauts from selling their memorabilia.
Camera equipment has been among the most popular, with a Hasselblad camera used by Apollo 15 astronaut Jim Irwin selling for $910,400 in 2014.
Other highlights of the sale included Dave Scott's flown Apollo 17 Robbins medal, which realised $67,292.
Only 80 Robbins medals were taken aboard Apollo 17, the lowest of any mission in the series.
