 I'm not going to write about all the constellations, that would be idiotic and take far too much time but this is just help understand when reading a star map, that the stars in the sky don't appear up there with little labels, hence you need to actually need to look for them; preferably in the right direction.

For an example; Andromeda, all of the stars included within said constellation, are shown to the left. Andromeda is found north of the celestial equator, and due to this Andromeda is only visible above 40°  south latitude. For those who want to view it from the southern area it lies below the hoizon.

It is one of the largest constellations at 722 square degrees, over 1,400 times the size of a full moon and ten times that of crux, the smallest constellation.

To the right is an image showing Andromeda in reality, the difference is clear between the map and the photograph.
