NIGHT
First, looking up to the sky we have to localize:
 Big Dipper (Ursa Major)
 Little Bear (Ursa Minor)
 The North Star (Polar Star)
1. Easily, if we are used to look up to the sky, we need just to look directly to the
Geographic North where there’s Constellation of Ursa Minor, and it is always
recognizable in our hemisphere; for this reason, we could find our fours Cardinal
Points.
2. INVERSE METHOD, while during some night Ursa Minor is less bright, we prefer
find Ursa Major, which is less surrounded itself with lot of stars than Ursa Minor.
Then, localized the Ursa Minor, we can notice that from the ending part of
constellation, where are located Dubhe and Merak, at a distance of 5 times
Dubhe-Merak there is Polar Star.
Polar Star, is always located in same direction because the over-line axis of Earth
revolution lies, casually, almost in correspondence of Polar Star.
