Astronomical quadrant Size:XS: 25 x 20cm removed the space-consuming transmission tunnelA 12 inch astronomical quadrant made by John Bird. Astronomical quadrants were used to measure the angle of a celestial object from the zenith. Operated in conjunction with a transit instrument, they could be used to check the running rate of astronomical clocks known as regulators. At sea a quadrant can be used to help fix a ship's position and to determine latitude. ca. 1767
