    Re: How does the AstraIIIb split mirror work?
    From: George Huxtable

    This matter of how light arrives at the eye via the unsilvered surfaces of
    the index mirror now seems to be resolved, to (at least) Ken Muldrew's
    satisfaction. Others may yet find a scrap of meat remaining on the the
    bone, to pick at.
    To me, it seems to have shown all the best features of how a mailing-list
    discussion ought to be conducted. Listmembers proposed various experiments,
    tried them out, argued about the results, argued about the underlying
    principles, tossed various ideas to and fro, in a spirit of courtesy and
    mutual respect, to reach a conclusion.
    "Well, he would say that, wouldn't he?" I hear you say, because my original
    suggestions were confirmed. But I think that all on this list are
    open-minded enough to be prepared to change their stance, and their minds,
    in the face of strong-enough evidence and argument that points another way.
    It's a real privilege to be a member of such a list as Nav-L. Thanks to Ken
    for raising an interesting question.
    It leads me to wonder how quickly and successfully science and
    understanding would have progressed, in the Days of Newton and Maskelyne
    and Sumner, if they had been able to argue with their contemporaries by
    email, instead of sending letters carried by packhorse and sailing ship.
