Meridians run between the North and South poles. In geography and geodesy, a meridian is the locus connecting points of equal longitude, which is the angle (in degrees or other units) east or west of a given prime meridian (currently, the IERS Reference Meridian). [1]
Note the observer's chair between the piers, and the narrow opening in the wall and roof for access to the sky. Because the telescope observes only in the meridian, no rotating dome is necessary. Meridian circles required precise adjustment to do accurate work. [17] The rotation axis of the main telescope needed to be exactly horizontal.
The meridian on the celestial sphere. An observer's upper meridian, a semicircle contains their zenith and both celestial poles; the observer's local meridian is the semicircle that passes through their zenith and the north and south points of their horizon.
