Rotary star map is best for beginners, while monthly star map usually gives more details of the night sky.
Keep in mind that the night sky changes from days to days and hours to hours. A monthly star map shows the night sky at about eight or nine
o'clock of that particular month. For every two hours gone, use the star map for the following month.
Star map is simple to use. Just hold it over your head and turn it until the direction indicated on the map points to the same direction in the field.
