The 88 constellations pages used as additional sources, are publicly shown here. This page should be restored by the professionals, as it clearly would present the quadrant information that is included on EVERY one of the constellation pages. Quadrant is a rectangular divisions on the celestial sphere that is used for finding constellations. The celestial sphere is divided into northern hemisphere and southern hemisphere with each hemisphere divided into four six-hour arcs. It is symbolized by using the capital letter N or S, followed by Q for quadrant, and quadrant numbers 1, 2, 3, or 4. However to determine exact quadrants, the midpoints of the constellations must be used.  First quadrant: 0h to 6h Second quadrant: 6h to 12h Third quadrant: 12h to 18h <li>Fourth quadrant: 18h to 24h</li> </ul> For example, the constellation <a href="http://en.wikipedia.org/wiki/Andromeda_%28constellation%29" title="Andromeda (constellation)">Andromeda</a> is located in NQ1, where this constellation is located in northern hemisphere in 1st quadrant. Another example, the constellation <a href="http://en.wikipedia.org/wiki/Sagittarius_%28constellation%29" title="Sagittarius (constellation)">Sagittarius</a> is located in SQ4, where this constellation is located in southern hemisphere in 4th quadrant.
