How and when to locate the zodiac constellations

How to observe the constellations?

To correctly identify the constellations, it is necessary to see the stars who draw their figures. People living in cities or surrounding areas are very few of them because the light pollution (light generated in excess by the man and escaping into the environment) adversely affects the visibility of the fainter stars. It is therefore recommended, seek a dark place. It is necessary first of all, if we learn in a rigorous and accurate, we begin by, that is the first we have seen and recognized in our lives.
From here, we're moving with a view of the constellations surrounding the first, provided we have a map the night sky or a guide to the naked eye. Once we have identified a constellation in the night sky, the other automatically will we, how difficult is the first, we must look to a person who knows one, just one, that is enough to start on the map. It is very easy, if we see the "Car or Big Dipper" in heaven and on the map else is there to find the next both in heaven and on the map. You can learn new constellations.
