Framed Print of Transit Instruments, Pais Observatory
Transit instruments were pivoted telescopes that allowed astronomers to time the passage of a star over the meridian (an imaginary line through the poles). As the heavens rotated, an astronomer would look through the transit telescope (aligned in the meridian) and note when a particular star crossed his field of vision. At the precise moment that the star passed, the astronomer noted the time via the ticking of a nearby astronomical regulator, an accurate clock used specifically for timing these transit observations. Without such measurements, the transit instrument wasn t able to do its job. A Mural Circle is an instrument used before the invention of the telescope to measure the angle above the horizon of astronomical objects as they crossed the meridian.
