Latitude Chart for Major Cities of the World

To aid in the polar alignment procedure (see page 16), latitudes of major cities around the world are listed below. To determine the latitude of an observing site not listed on the chart, locate the city closest to your site. Then follow the procedure below:

Northern hemisphere observers (N): If the site is over 70 miles (110 km) north of the listed city, add one degree for every 70 miles. If the site is over 70 miles South of the listed city, subtract one degree per 70 miles.

Southern Hemisphere observers (S): If the site is over 70 miles (110 km) north of the listed city, subtract one degree for every 70 miles. If the site is over 70 miles South of the listed city, add one degree per 70 miles.

Star Locator

Following is a list of bright stars with their R.A. and Dec. coordinates, along with the Northern hemisphere season when these stars are prominent in the night sky. This list will aid the observer to find alignment stars at various times of the year. For example, if it is a midsummer evening in the Northern hemisphere, Deneb in the constellation Cygnus, would be an excellent alignment star, while Betelgeuse could not be used because it is in the winter constellation Orion and thus below the horizon.
