The zenith.
The microscope has two systems of lenses: the ocular lens into which the observer looks; and objective lenses placed directly above the object being observed.
The term that describes the very top of the sky is the "zenith." It refers to the point directly above a particular location or observer, where the sky seems to meet the ground.
The point just overhead is called the zenith. The objects visible at that point depend on the date, the time of day or night, and the observer's location.
The imaginary point in the sky directly above an observer on Earth is called the zenith. It represents the highest point in the sky that an observer can see when looking straight up.
Appears directly above sodium
Polaris is a star which is directly above the North Pole and therefore appears to be stationary as the Earth rotates on its axis.
The Pole Star appears to remain stationary because it is directly above the North Pole.
The zenith is the point directly overhead in the sky, while the horizon is the line where the sky appears to meet the Earth. The zenith is the highest point above an observer, while the horizon represents the farthest visible point on the Earth's surface.
