Bill Hammack "The Engineer Guy" video
Bill describes the Alignment Optical Telescope used in the Lunar Module on the Apollo missions to the moon. This telescope took star sightings which were used to align the Module's guidance system.

Bill shows how the telescope used an Archimedes spiral inscribed on its eyepiece to replace the heavy motors, worm gears, and rigid tracks used in a traditional sextant — this shaved weight from the Lunar Module and allowed it to carry more fuel.

I thought that this was a really excellent video explaining the operation of the Apollo Alignment Optical Telescope.
