How do i predict star positions using star charts?
Star charts provide a static map based on two coordinates: Right Ascension (in hours, minutes, and seconds, range 0:00:00 to 23:59:59) Angle of Declination (in degrees +90 to -90) Angle of Declination is the easiest to explain – it’s the number of degrees from 0 to 90 that a star is above or below the celestial equator. (Positives are north, negatives are south.) The hour of right ascension: the zero point is known as the vernal equinox point (also known as the First Point of Aries), which is the place in the sky where the Sun crosses the celestial equator at the March equinox. The sky is charted from there.
