    Tim Imgham, you wrote:
    "Thank you for your detailed response.  it will give me much to think about and get my mind around."

    Well, my response was supposed to be a conversation-starter, so please do feel free to ask questions, comment, converse! :)

    You added:
    "Being now an ancient mariner and having recently acquired a good second hand Alpha 40, I thought I should go back to square one and do a proper course in CN, with the ultimate aim of actually being able to do a Lunar that has some pretence of competence."

    Sounds good. I don't have any currently scheduled (last batch was in May), but you might enjoy reading about my workshops, including lunars. And you might enjoy my essay on Easy Lunars. Lunars certainly don't have to be hard, but they're always a challenge for our sextant skills. I originally wrote that essay in 2004 which, upon reflection, was closer to your 1994 "first proper offshore sail" than it is to the present day!

    You concluded:
    "I am checking the "official" precise location of the Time Ball at Sydney Observatory (when installed, in 1858) but can't currently visit them as they are 'closed for historic renovations'."

    What draws you to this topic of historical latitudes and longitudes? Do you have a goal in mind? Just general interest?
