Geoffrey, > It is easy to determine the Index Error of a marine > sextant, but not of bubble sextants. Easy or not, but I infer from your message that you can find the IC of your bubble sextant SOMEHOW. I don't see any way to do this at all, except taking an altitude from a known position. This can be done once in a while, but certainly not before or after an observation, if the purpose of the observation is to find this position.
