Q. 3) se2tant se2tant is an instrument used to measure the angle bet+een an t+o visible obects. &ts primar use is to determine the angle bet+een a celestial obect and the hori4on +hich is kno+n as the obect"s altitude. aking this measurement is kno+n as sighting the obect6 shooting the obect6 or taking a sight and it is an essential part of celestial navigation.
