    Re: Sextant of the future?
    From: Francis Upchurch

    Fantastique Andres!

    I wondered when this sort of thing would be developed. Anyone know when it is likely to be available on the market? Probably at a premium price intially?

    Also have wondered if something maybe a bit simpler could be done with smart phone and appropriate app?

    Iv'e recently been experimenting with my increased accuracy nocturnal (well really a polarum as described by Tony Crowley.)

    I can get latitude from the angle between polaris and  alkaid or e Cassiopiae, + a sextant polaris  alt. And then , looking again at polaris , can get longitude from the angle between Kochab and polaris..(need GMT and LHA aries for that.)

    So question for the app experts. Could you use a smart phone to take a picture of polaris and the circumpolar stars, including kochab, alkaid and e cas, Knowing time and polaris alt from either a seperate sextant reading or maybe even the inclinometer on the phone and software to give approx lat and long?

    Just a thought and maybe a challenge to app developers in Navlist?

    What a wonderful world we live in! Wish i was 25 again!

    Francis
