    Re: Aligning a transit telescope to the meridian
    From: Bill Noyce

    Measure the azimuth of a bright near-equatorial star at, say, 15
    degrees altitude in the east, and again 15 degrees altitude in the
    west.  (Mark these out on the ground, using local landmarks, not with
    a compass.)  Split the difference to get a north-south line.  You
    might have to do the two measurements at different times of the year.
    
    Do the same with the sun, around a solstice, or else applying some
    correction for its changing declination.
