    Re: Longitude by lunar and solar transit
    From: Peter Monta

    Here is the next section in Chauvenet, extending the method for theodolites (for the "travelling observer"):
    The error due to off-meridian observations is given on page 379; within 15 degrees of the meridian it is very small.

    Cheers,
    Peter
