Azimuth is the angle, typically using true north as zero degrees to an object from viewers location. An altitude (if expressed as an elevation angle from the viewer) provides a line of sight to an object in space. If you were standing at a point and facing true north and there was an airplane flying at 20,000 ft and you knew the elevation angle you could compute the range and have an (X,Y,Z) location for the object.
location of a star
The azimuthal grid is a coordinate system that stays still while the stars move across it on the sky (the celestial sphere). It measures the altitude above the horizon and the azimuth (position along the horizon) of the celestial object at a particular time, for a particular place.

You have to convert them to Polar Points or the Azimuth points and use the angle difference.
An azimuth circle is a device used for measuring azimuths, a graduated circle on a sight, gun carriage, searchlight, etc.
North
Altitude and azimuth are important for determining the position of celestial objects in the sky. Altitude measures the angle above the horizon, while azimuth measures the direction from north. Astronomers use these coordinates to locate and track stars, planets, and other astronomical objects. Similarly, hikers and navigators use altitude and azimuth to find their way using landmarks and the positions of the sun and stars.
The azimuth and altitude of Sagittarius depend where you are on Earth and the date and time. The altitude can be anything form 0-90, and the azimuth 0-180.
As of 2021, Betelgeuse has an azimuth of around 225 degrees and an altitude of about 27 degrees when observed from the northern hemisphere. These values will change throughout the night and over the course of the year due to the Earth's rotation and orbit.
Azimuth = 315° (True) Altitude = 0
Yes, the rotation of the Earth affects the azimuth and altitude of celestial objects, as they appear to move across the sky due to the Earth's rotation. The azimuth (horizontal direction) changes as objects rise in the east and set in the west, while the altitude (vertical angle) changes as objects rise higher in the sky and then descend.
The variation of the apparent azimuth and altitude of everything we see in the sky is the result of Earth's rotation.
The altitude of a star that is setting due west is 0 degrees, as it is on the horizon. The azimuth would be 270 degrees if we consider 0 degrees as north and increase in a clockwise direction.
An object seen halfway between the horizon and the zenith has an altitude of 45 degrees.An object seen due east of the observer has an azimuth of 90 degrees.

The two types of sundials are altitude and azimuth sundials.

Three common reference points are azimuth (direction along the horizon), altitude (height above the horizon), and declination (angle north or south of the celestial equator). These points are used to describe a star or planet's location in relation to an observer's position on Earth.
