declination axis

The axis at right angles to the polar axis about which a telescope on an equatorial mounting is turned in order to make adjustments in declination. The optical axis then follows a particular hour circle across the sky.

Declination Axis

one of the axes of an equatorial mount of a telescope. The declination axis is perpendicular to the polar axis. The telescope is rotated about the declination axis as it is directed to a given point on the celestial sphere.
