Using this planisphere, determine the latitude of the place, knowing the meridional height of the given star. For example, a star with d = + 37њ has an altitude of 78њ at the moment of climax above the South point. Determine the latitude of the location.

Let us set the planisphere so that the celestial parallel + 37њ rises above the South point to a height of 78њ, and we count the number of degrees on the meridian against the pole of the world, in this case N.R .; then we get that the required latitude of the place is + 49њ (north).
