Locations in the sky are much the same as they are on earth, but are given as Declination and Right Ascension, not latitude and longitude. Declination is just like latitude. A star's declination describes its location north or south of the celestial equator. Declination is measured in degrees of arc. Positive declinations are in the northern half of the sky.
Negative declinations are in the south.
A star's east-west location is called Right Ascension. Right Ascension is measured in hours and minutes of time. The Right Ascension scale runs from 0 hours to 24 hours. Using the chart, check locations of these well-known stars. Capella 18 5.2 hrs.
