    Hi Alain,
    
    when observing in binoculars, identification is much safer if the track's
    intersection angle, position (and speed) are given in relation to a line
    between two stars in (or near) the FOV, or the vertical (or horizontal)
    line, counting clockwise like azimuth,
    
    rather than trying to extrapolate the culmination point or a horizon point,
    or the inclination, and the height.
