Instruments such as a sextant or a quadrant can be used to determine the altitude of the North Star. By measuring the angle between the North Star and the horizon, navigators can determine their latitude.
The point on the horizon that is due west has an altitude of zero and an azimuth of 270 degrees.

The North Star, also known as Polaris, is commonly used for navigation to determine the direction of due north in the Northern Hemisphere. It remains almost stationary in the night sky and can be found by locating the Little Dipper constellation.

celestial navigation
The device used to determine the altitude of the North Star (Polaris) is called an astrolabe. An astrolabe is an ancient astronomical instrument that allows users to measure the angle of celestial objects above the horizon. By aligning the astrolabe with Polaris, one can determine their latitude based on the altitude of the star. This technique has been used for navigation and understanding one's position on Earth.
Zero. (It's on the horizon.)
To determine your latitude in the northern hemisphere using a star, measure the angle between the horizon and the star using a sextant. This angle is called the star's altitude. If you know the star's declination (which is constant), subtract it from 90 degrees minus the star's altitude to find your latitude.
The idea is there, but a couple of important terms are swapped.The altitude of the North Star above the northern horizon is approximately equal tothe observer's north latitude.
The altitude of the North Star will not change from any point on Earth. However, the declination changes depending upon where you are and when - It is less than 90 degrees.
To determine your direction using the North Star, locate the North Star in the night sky, which is always positioned in the north. By facing the North Star, you will be facing true north, helping you find your direction.
If you are at the North Pole, you'll see the star Polaris near the zenit (altitude almost 90 degrees).
Northville, MI is at 42 degrees, 26 minutes North. The altitude of the North Star is between 42 degrees and 43 degrees, depending on the time. (Polaris isn't exactly at the North Pole; it is about 1/2 degree off.)
The altitude of polaris for an observer is always the same as your latitude so it would be 64oN
One method to determine true north without a compass at night is by using the stars. You can locate the North Star (Polaris) which is positioned close to true north. Draw an imaginary line from the North Star to the ground to find where true north lies.
