number of hours, minutes and seconds that they lag behind this coordinate after it passes overhead
moving westward.
Given the celestial coordinate system, it now becomes possible to find celestial objects by translating
their celestial coordinates using telescope pointing positions. For this you use setting circles (if you
have the Firstscope EQ - equatorial mount models) for R.A. and Dec. to find celestial coordinates for
stellar objects which are given in star charts and reference books.
B.
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 3.A).
