    Time-lapse movie with stars
    From: Peter Monta
    Date: 2018 Jan 3, 18:04 -0800
    This time-lapse movie from a cargo ship is perfect for celestial navigation:

    At 8:30 the latitude of the ship is marked out very clearly on the sky.  :-)

    No timestamps, so longitude is a problem, but maybe a kind of dead-reckoning using the CN-derived ship's heading could be attempted.  Time intervals are available from the stars, the Sun, or maybe also the cloud-speed (very roughly).

    Cheers,
    Peter
