(above) A detail from a British Astronomical Association star chart drawn by the Dutch amateur astronomer Wil Tirion shows some southern hemisphere stars. The coordinates of right ascession and declination have been corrected for precession - a movement of the Earth's axis - so the stars are drawn as they will appear in the year 2000. The Southern Cross is present, as is the larger Magellanic Cloud, which is a compansion galaxy to our own.
