Anonymous users2024-02-07The principle and method of making an astronomical telescope are as follows:
1. Principle. The objective lens is a convex lens, and the light is concentrated to form an inverted and reduced real image, which is magnified by the eyepiece to observe the details of the object. Astronomical telescopes are the main tools for observing celestial bodies and capturing celestial information, and their principles are basically the same as those of binoculars, but in order to gather more light, the aperture is increased; In order to increase the magnification, the lens barrel is lengthened.
2. Production method.
Materials: Steps: Reading glasses, magnifying glasses, glue, adhesive tape, and discarded roll paper tubes.
1. First prepare reading glasses, magnifying glasses, glue, adhesive tape and discarded paper rolls.
2. Then glue the magnifying glass and the paper tube together to form the eyepiece tube, pick up the eyepiece and the objective lens barrel at the same time, keep the eyepiece at a distance of 5 cm, and slowly move the objective lens tube.
3. Finally, until the two lens barrels can clearly see the scene, note the distance between the eyepiece and the objective lens.
4. Complete the remaining paper tube, roll it into a cylinder with a piece of cardboard, and pull it back and forth.
About Astronomical Telescopes:
Astronomical telescopes are the main tools for observing celestial bodies and capturing information about celestial bodies. Humans are expected to have telescopes in the electromagnetic band, neutrinos, gravitational waves, cosmic rays, etc.
Since Galileo Galilei built the first telescope in 1609, telescopes have continued to develop, from optical bands to full bands, from the ground to space, telescopes have become more and more sensitive to observation, and can capture more and more celestial information.
Telescopes originated from glasses. Humans started using glasses about 700 years ago. Around 1300 AD, the Italians began to make reading glasses with convex lenses.
Around 1450 AD, myopic glasses also appeared. In 1608, an apprentice of the Dutch spectacle maker Hans Ripachy stumbled upon the idea that stacking two lenses on top of each other would allow for a clear view of things in the distance.
In 1609, when the Italian scientist Galileo Galilei heard about this invention, he immediately built his own telescope and used it to observe the starry sky. Since then, the first astronomical telescope has been born.
The Datian Region Multi-target Fiber Optic Spectroscopy Telescope (LAMOST, also known as Guo Shoujing Telescope) is composed of a telescope with an effective aperture of 4 meters and an optical system of Schmidt type, which is located at the Xinglong Xingzhizhi Observatory of the National Astronomical Observatories of the Chinese Academy of Sciences. It applies active optics technology, making it the world's largest optical telescope with a large aperture and a large field of view.
The pole is an equatorial mount.

**Proportional to the square of the aperture (i.e., the area of the primary mirror). If you have money, you can see details such as the spiral arm of the extragalactic galaxy with an aperture of more than 200mm, and a spot of light below 200mm. The same is true for nebulae, the stars are one point anyway, even with Hubble, but large aperture can distinguish more binary stars, polyconjunctions. >>>More
Summary. Hello! When choosing a good astronomical telescope, there are several factors to consider: >>>More
Beijing Galaxy Telescope Answer:
The gap between astronomical telescopes is very large, and our ordinary junior astronomy enthusiasts can choose non-professional mirrors (professional mirrors are very expensive, and they are generally used for professional observation). **In the 1000-2000 yuan or so low-end astronomical telescope can be, of course, if you are very passionate about astronomy, for the observation effect of high requirements, you must choose the high-end telescope, refraction and reflection have their own advantages and disadvantages, mainly depending on what you want to observe, choose the best one for yourself; >>>More
Friend, after reading the ** you sent, I can tell you that the effect of these pictures is not reached, and it is not enough to see only a small bright spot, but it is almost, you can still vaguely see that there are two small edges and corners next to the stars, which is a graphic halo, but it is impossible to distinguish that it is a ring, such a telescope can only be used for sightseeing, at most you can see the lunar crater, if your main purpose is astronomical observation, such a telescope you will regret when you buy it!
