Declination corresponds to latitude and right ascension to longitude. There are no roads in the sky, so knowing an object's coordinates is crucial to finding it in your telescope. Let's use our imaginations and picture the latitude–longitude grid on the planet as the surface of a flexible, transparent soccer ball.

At most places on the earth's surface, the compass doesn't point exactly toward geographic north. The deviation of the compass from true north is an angle called declination (or magnetic declination). It is a quantity that has been a nuisance to navigators for centuries, especially since it varies with both geographic location and time.
