The instrument used by astronomers to study light given off by stars is called a telescope, but one may add to the telescope an instrument called a spectrometer if you want to split the light into its components and using this determine what the stars are made of.
A transit circle is used to measure the angle of a star above the horizon when is it due south or north, and this enables the declination to be calculated, which is the angle north or south of the equator on the celestial sphere, and it is also the latitude where that star appears overhead.
The right-ascension is found from the clock time that the star crosses the central crosswire on the transit circle, which happens when it lies exactly north or south. The right-ascension is the time after which the star crosses the meridian after the First Point of Aries, which is the direction of the Sun's crossing into the nothern half of the sky at the vernal equinox. It is the direction defined by the intersection of two planes, the Earth's orbital plane and the Earth's plane of axial rotation.
Because of precession the First Point of Aries moves a small amount each year, so stars' positions are always quoted for a given epoch, e.g. 1950.0 or 2000.0 etc.
We use angular measuring instruments to measure the angular altitude of a star above the horizon. For navigational purposes, this is typically a sextant, so-called because its angular measuring device is one-sixth of a circle. (Older measuring devices such as the octant and quadrant, measuring one eighth or one quarter of a circle, are seldom used.)
The light collected by the telescope can be passed through a prism to break it up into its spectrum.

The instrument you are thinking of is the sextant and it was independently invented by two men at around the same time, John Hadley and Thomas Godfrey.

To break an object into colors you use a prism
A spectrometer, which can be a crystal prism, or a diffusion gradient.

Zero. (It's on the horizon.)
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.
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.)
there is no latitude or longitude of north star it just have altitudeand if u are in NH u can find your latitude if know what is altitude of north Star
The altitude of polaris for an observer is always the same as your latitude so it would be 64oN
some time there is a Storm and you can't see the star so that is the disadvantage of using a north star
Look for the North Star or Polaris. It sits right over the North Pole of the Earth. It is the last star in the Little Dipper.
Yes. Two thousand years ago, the current Polaris was not the North Star. By the end of the 21st Century it will not be above the North Pole.
