astronomical telescope
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.

Starburst Astronomical telescope
The Singtron Astronomical telescope was a professional stargazing device with multiple models to choose from. Two of the entry-level models were the Singtron 80EQ and the Singtron 127Slt. The Starlight 80EQ was a telephoto refraction telescope with a diameter of 80mm and a focal length of 900mm. It was suitable for observing bright celestial bodies such as the moon and Jupiter. It was equipped with the EQ1's equator mount and had a full range of accessories, including eyepieces, star-seeking mirrors, and zenith mirrors. It could also be used with mobile phones and cameras. The Singtron 127slt was an automatic star-finding telescope. It was portable and reliable, suitable for beginners. This telescope was a catadiopretic Marka with a diameter of 127mm and a focal length of 1500mm, allowing more details to be observed. As for which telescope was better, it depended on the individual's budget and needs. Singlar's product prices ranged from entry-level to professional, so consumers could choose the right model according to their budget and needs.

A telescope that can capture Jupiter
To take pictures of Jupiter, one could use a variety of binoculars. If one wanted to take a photo of Jupiter like the winner of the 2011 Greenwich Royal Observatory photography competition, one would need an astronomical telescope with a diameter of at least 350 millimeters and professional astronomical photography equipment. However, for ordinary observation and photography, small astronomical telescopes could also be used to observe Jupiter. They could see the bright and dark clouds of Jupiter. If they were lucky, they could also see the Great Red Spot. They might also see some of Jupiter's satellites, such as the Galilean satellite. In addition, the Webb Space telescope's near-infrared camera could capture Jupiter. The photos not only showed Jupiter's features in detail, but also observed auroras, storms, and distant galaxies. The Hubble Space telescope could also observe and photograph Jupiter. It captured the color changes in Jupiter's cloud belt.
