Xia Lang's novel of telescope
" Xia Lang's Spyglass " was a novel by Zhang Chu. It was included in his collection of short stories, such as " Sheep Heading West " and other collections of short stories. Zhang Chu was a "post-70s" writer. He had published many collections of novels and won many awards such as the Lu Xun Literature Award and Yu Dafu's novel award. His works mostly reflected the characteristics of "blade-like narration", which expressed the mottled splendor of society through a narrow and slender perspective embedded into the hearts of characters or the gaps of events. Xia Lang's telescope might also have such a style. Read more exciting novels for free
telescope
A telescope was an optical instrument used to observe, aim, and measure distant objects. The angular magnification was generally greater than 1. In a broad sense, it also included astronomical instruments that observed electromagnetic waves invisible to the human eye. It was commonly used in ground observation, astronomical observation, astrophotography, space exploration, and other fields. In 1608, Hans Lieber, a Dutch glasses merchant, accidentally discovered that two lenses could be used to see distant scenes, making the world's first binoculars. In 1609, the Italian physicist, galilei galilei, was inspired to make the first refraction telescope. The telescope began to be used in the field of astronomy. Later, many scientists, such as Johannes Kepler, Isaac Newton, Cassegrain, Bernhard Foldomar Schmidt, etc., optimized and improved it, producing refraction, reflection, catadioprism, and many other types. After more than 400 years of development, the telescope had become more powerful and had a longer observation distance. In modern times, with the development of science and technology, telescopes were no longer limited to ground observation. They began to enter space, and new types of telescopes such as radio telescopes and space telescopes appeared. It was mainly composed of optical system, mechanical structure, pointing system, image acquisition system, electronic system, etc. By magnifying the angle of distant objects, the human eye could see details with smaller angular distance. It could also send the light beam collected by the objective lens into the human eye, allowing people to see dark objects that could not be seen before. The typical models were the Very Large telescope, the China Sky Eye, the Hubble Space telescope, the Big Bear Lake Solar telescope, etc. When it came to choosing a telescope, novices often made mistakes. For example, they thought that the higher the magnification, the clearer it was. In fact, the optical configuration was the real deciding factor. There were fixed-power and variable-power binoculars. The fixed-power binoculars had stable imaging, a large field of view, and a strong sense of comfort. For example, a 10X50 binoculars represented 10x amplification and 50 apertures. A variable-power binoculars had a multiple range that could be adjusted. For example, 10 - 20*50 meant that the multiple could be adjusted between 10 - 20 times. Astronomical telescopes were astronomical observation devices that collected celestial radiation and determined the direction of the radiation source. For more than 300 years before the first radio telescope was built in the 1930s, astronomical telescopes were basically equivalent to optical telescopes. According to the principle of imaging, optical telescopes could be divided into refraction telescope, reflection telescope, and catadioptical telescope. There are many famous telescopes in the world, such as China's 500-meter spherical radio telescope. Fast (China Sky Eye) was the world's largest fixed antenna radio telescope by 2023, and the Greenbank Radio telescope (Gbt) was the largest mobile antenna radio telescope on Earth by 2024. The Hobby Eberly telescope, the Caique telescope, the Canary Grand telescope, the South African Grand telescope, and the Atacama Large Millimeter Wave Array were also famous telescopes. They each had different characteristics, functions, construction locations, and funding sources.

Xia Zhixing and Lin Lang's comic
There was a manga called " Big Dog Bullies the Master " that was related to Xia Zhixing and Lin Lang. In this manga, the school hunk Xia Zhixing was unwilling to expose his identity as a game streamer in reality, so he looked for the ghost scholar Lin Lang to be his " face replacement." Lin Lang had been eyeing Xia Zhixing for a long time, and there was also the sentence " Senior, the reward I want is you." Such a scenario. The novel " Glittering Four Seasons " is equally exciting.

A telescope was an optical instrument used to observe, aim, and measure distant objects. Its angular magnification was generally greater than 1. In a broad sense, it also included astronomical instruments that observed electromagnetic waves invisible to the human eye. It was mostly used in ground observation, astronomical observation, astrophotography, space exploration, and other fields. In 1608, the Dutchman Hans Lieber made the world's first binoculars. In 1609, the first refraction telescope was made by Galilei, and the telescope began to be used in astronomy. An astronomical telescope was an astronomical observation device that collected celestial radiation and determined the direction of the radiation source. It usually referred to an astronomical optical telescope with light gathering and imaging functions. According to the principle of imaging, it could be divided into three categories: refraction telescope (using a lens to produce a mirror), reflection telescope (using a mirror to produce a mirror), and catadiopretic telescope (using both a lens and a mirror to produce a mirror). It was not recommended for beginners to buy expensive equipment at the beginning when choosing an astronomical telescope. For example, the price of the more affordable Singterra 80EQ (about 600 yuan) was more suitable for entry. Although it was cheap, it could shoot the three common planets, the moon, M42, and so on. When choosing two products with the same price but different brands and a difference of 1 - 200, the difference was not big for beginners. They could choose the one they liked more. There were many brands of astronomical telescopes, such as Star Terran, Meade, Cinda, Exploration Science, Boguan, etc. Among them, Star Terran was the best-selling. It was recommended to give priority to well-known brands and avoid unknown small brands to avoid stepping on the pit. The budget astronomical telescope worth buying in 2024 is the Celestron StarSense Explorer DX130AZ.(Price: $379.95, original price: $479.95, 5.1-inch large aperture, 650mm focal length, equipped with StarSense sky recognition technology, etc.), Orion Observer 90mm telescope (Price: $379.95, 90mm objective lens diameter, 86.4cm tube length, comes with two eyepieces), Sky-Watcher Classic 200 (Price: $550.00, original price: $655.00, equipped with 8-inch mirror and other advantages), Celestron 76mm Sign Series Firstscope (Price: $79.70), etc. The novel "Hundred Years of Spaceship" is equally exciting.

You might want to ask about the catadioptical telescope. The catadiopretic telescope was an optical telescope with an objective lens that combined reflective and reflective elements. It added a refraction element to correct aberrations on top of a spherical mirror. This kind of telescope had the characteristics of a large field of view, a large focal ratio, and a relatively good image quality. It also combined the advantages of a refraction mirror and a reflection mirror, such as a large field of view, good image quality, a short tube, and easy to carry. However, it also had shortcomings such as relatively high cost and difficult maintenance. The light was first bent through a lens, then reflected and focused by a mirror. In 1931, the German Schmidt invented the optical system of the Schmidt telescope by placing an aspheric thin lens in front of the spherical mirror. Later, the Schmidt-Cassegrain telescope, which was based on the Schmidt star camera and used the Schmidt correction plate to correct spherical aberrations, appeared. The Soviet scholar, Marksutov, used a crescent-shaped lens as a correction lens to create the Marksutov-Cassegrain telescope and other types. There were many brands of catadioptical astronomical telescopes on the market. For example, the Boguan 150/1800 catadioptical astronomical telescope EM10 equator instrument version used a high-performance, high-quality three-piece Marksutov-Cassegrain system. It was composed of a crescent mirror and two spherical mirrors. The image was clear, the contrast was high, and the color difference was effectively controlled. It could be used for deep space observation and to appreciate the details of the moon and planets. Meade's Schmidt-Cassegrain catadiopretic telescope was also well received, and Takahashi's FSQ series of photographic lenses were specially designed for astronomical photography, of which the FSQ85 and FSQ106 were both highly praised. The novel "Hundred Years of Spaceship" is equally exciting. Everyone is welcome to click and read it!
