Using the celestial coordinate system, it becomes possible to find celestial objects by translating their celestial
coordinates, using telescope pointing positions. To do this, you use your RA and DEC setting circles to find celestial
coordinates for stellar objects. These coordinates are given in star charts and reference books.
Polar Alignment
To make tracking the stars easier, rough polar alignment is required.
1. The right ascension (polar) axis should be pointed towards the North Pole (see the illustration below).
2. The equatorial mount should be level.
3. Your latitude should be set (see previous section on "Setting Latitude" ).
