Meridian circle - an instrument for timing of the passage of stars across the local meridian, an event known as a transit, while at the same time measuring their angular distance from the nadir. These are special purpose telescopes mounted so as to allow pointing only in the meridian, the great circle through the north point of the horizon, the zenith, the south point of the horizon, and the nadir. Meridian telescopes rely on the rotation of the Earth to bring objects into their field of view and are mounted on a fixed, horizontal, east-west axis.

The whole in-strument can revolve 180° in azimuth about this pillar. The tele-scope has a micrometer at its eye-end, and it also carries a dividedcircle provided with a fine level. A second level is provided,whose use is to make the rotation axis horizontal. The peculiarfeatures of the zenith telescope are the divided circle and its at-tached level.
