#azimuth

• altazimuth — An astronomical instrument or mechanical mount utilized for determining the position of celestial bodies or for guiding telescopes and cameras, structurally characterized by rotation around two perpendicular axes: a horizontal axis (for measuring altitude or height above the horizon) and a vertical axis (for measuring azimuth).
• Azimuth — The horizontal angle formed between the meridian plane of a location (North direction) and the vertical plane passing through the observed point or target celestial body, measured clockwise from 0° to 360°; a horizontal coordinate element used for spatial orientation, topography, and marine or aerial navigation.
• Azimuth — The horizontal angle measured clockwise (from 0° to 360°) between the North direction of a reference meridian and the direction toward a given point on the Earth's surface or the projection of a celestial body on the horizon.
• Azimuthal — Pertaining to azimuth, belonging to azimuth, or carried out within the horizontal plane of the azimuth; often used to describe telescope mounts, map projections, or measuring instruments that utilize horizontal coordinates based on the angle formed with the North direction.
