The sky at your fingertips

In this activity we will build a simple cross-staff to measure angles. We will show how angular distances can be measured using this simple self-made aid in order to determine the position of a celestial object on the celestial sphere. (Please note that this activity can be followed by the activity: Chasing the Moon )
