There was a fellow with the U.S. Navy who explored accuracy of
standard sights in 1960 or so, testing various sextants and
telescopes.  Unfortunately, I don't recall much more detail.  His
paper was referenced here in 2005 or so, and Joel ____ commented on
his paper. Joel is the guy involved with Tamaya sextants, who I
believe had the Land and Sea online sextant store, who stopped
posting here about a year ago.
