    Re: Self Taught Celestial

    I can only say that once successful sights have been taken from a boat enthusiasm is very likely.
    I have taught my wife and two of her friends to use celestial with Kolbe's LTA, sextant and a watch with known rate, plenty of laughter and surprisingly rapid progress.
    True I doubt the friends could navigate without quick brush up of how, but they got good enough to find land in one day (worst plot was 6' when the first few shots where discarded).

    As an aside I made them "Bris Pendants", merely 16mm brass tubing cut into 10mm lenghts with glass part held in by O-rings.
    Bris sextant is a "sunset repeater" according to Sven Yrvind (inventor), it can give ones position to surprising accuracy if calibration procedure is followed (I usually calibrate them several times enter data into a spreadsheet to compare).
