in order to read the altitude properly
To determine the altitude of an object in the sky using an astrolabe, you would align the sighting arm with the object. Then, you would read the degree scale on the astrolabe where the sighting arm intersects it. This reading would give you the altitude of the object above the horizon.
An astrolabe is an old instrument used to calculate the position of celestial bodies. Here are some sentences.I found an antique astrolabe in an old store.An astrolabe was used before the sextant was invented.Polish that astrolabe so it doesn't tarnish.
The scientist used an astrolabe to find the altitude of the sun and stars.
what does aastrolabe
Astrolabe, the son of Heloise and Abelard, went on to become a successful canon lawyer. There is no record of Astrolabe having children, so it is unclear if he had descendants.
The astrolabe must be level in order to read the altitudeproperly.
To read an astrolabe, level the plum bob, the degree scale, the altitude, and the protractor.

An astrolabe and a protractor are both instruments used for measuring angles. The astrolabe, an ancient tool, was primarily used in astronomy for determining the positions of stars and celestial bodies, while a protractor is a simpler, more modern device used mainly in geometry for measuring angles in two-dimensional shapes. Both tools share a circular design and allow users to read angles, but the astrolabe incorporates more complex features for astronomical calculations.
An astrolabe is an angle-measuring device, vaguely similar to a sextant or an octant. Holding the astrolabe by a cord, one sights through a set of peepholes to observe a star, and you can then read the angle of elevation of the star above the horizon. It's not especially accurate, particularly not when on the pitching deck of a ship at sea. Columbus would have used this device to measure the elevation of the north star Polaris above the horizon, giving him his latitude (at least, approximately...). In order to calculate longitude, one also needs an accurate clock, which Columbus did NOT have.
I think at your reading level and with your parents permission you should.
== == the astrolabe is to find the altitude of a stellar object
