PIX4585211: Equatorial sundial - Equatorial Sundial - The equatorial sundial has the particularity of having its graduation table located in the plane of the Earth's equator. As a result, the style (the metal stem that gives the shade) is perpendicular to the table, although always directed towards the polar star. In an equatorial sundial, the planar surface that receives the shadow, is exactly perpendicular to the gnomon's style. This plane is called equatorial, because it is parallel to the equator of the Earth / Bridgeman Images
