In mapping the surfac e of the Earth, lines of longitude ar e drawn between the North and South Pol es and lines of latitude are drawn in an East-W est direction, parall el to the Earth's equator . Similarl y, imaginary lines have been drawn to f orm a latitude and longitude on the c elestial spher e. These lines ar e known as R R i i g g h h [...]

Any point on the cel estial equator (such as thee const ellations of Orion, Vir go, and Aquarius) is said to have a Declination of zer o, shown as 0 ° 0' 0". All cel estial objects theref ore may be loc ated with their celes tial coordin[...]

1. Release the Azimuth l ock (30)of the Azimuth base, so that the entir e tel escope-with-mounting may be r otated in a horizontal dir ection. Rotate the tel escope until it points due North.
