    Re: Lunars with SNO-T

    Dear Fred,
    I just posted my second series of Lunars made 2 hours ago.
    (Taking into account all advises I got on the first series)

    But do you agree that that bad observation HAD to be rejected?
    It was evident to me immediately when I read my sextant.
    My reason and all what I know about statistics imply this.
    
    I suppose the reason of that blunder was incorrect time recording.
    My (easily solvable) problem is that I have no watch that I
    can read in the darkness and without eyeglasses.
    So I am just thinking of buying a good large diameter
    split-second-hand stop watch, as in Bruce Bauer,
    page 141. (I see some of these in my favorite
    Ukrainian web store:-)
    In the observations I reported I used the
    "Old Flegmatic British Merchant Mate" method as described
    in Bruce Bauer, same page:-)

    I also like it. Still have to try really large distances.
    (It allows to 140 degrees!)
    I am afraid I will need another place than my balcony for this:-)
    
    Alex.
