Does anyone know how accurate (i.e., level) the surface figure of a sheet of black glass must be to serve as an artificial horizon? In particular I am trying to determine the point beyond which additional accuracy is irrelevant in terms of the result, given the other variables in a sighting with a hand-held sextant. best -p --~--~---------~--~----~------------~-------~--~----~ Navigation List archive: www.fer3.com/arc To post, email NavList@fer3.com To , email NavList-@fer3.com -~----------~----~----~----~------~----~------~--~---
