How much does it cost to buy a better telescope?

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;

The refractive aperture is relatively small, the focal length is relatively long, and the realization multiple is relatively high, which is more suitable for seeing the single planet and details, but it is easy to maintain, simple to operate, and the low-end refractor is relatively cheap, which is more suitable for beginners.

The reflective type has a large aperture, a short focal length, and a relatively low realization multiple, which is more suitable for seeing a large area of starry sky and a large observation field, but it needs to be coated once every five years or so.

The realization multiples mentioned above are relatively speaking, the magnification of astronomical telescopes is directly related to the eyepieces, and the eyepieces that are standard with each model are different and cannot be generalized. For beginner astronomy enthusiasts, it is still recommended to choose the refractive type.

For entry-level astronomical telescopes, the Centron 90EQ (refractive type) and 130EQ (reflective type) are both good choices.

90EQ This can see the crater on the surface of the moon, can see Saturn, Jupiter, Jupiter moons, etc., can also view the scenery, can see the trademark of one or two kilometers of air conditioning, this basic configuration is very good, the imaging effect is also great, ** at about 1600 yuan.

130EQ can see the craters on the surface of the moon, Saturn's rings, Jupiter, Jupiter's cloud belts, Jupiter's moons, etc., and 130EQ is basically a civilian astronomical telescope that can shoot nebulae with the lowest aperture requirements after being connected to the camera. **Around 1500 RMB. The relative aperture of 130EQ is large, and the observation field is large.

You can go to the Galaxy Telescope Knowledge Zone to see, you can directly search for "Galaxy Telescope", there is a lot of relevant knowledge about the purchase, maintenance and use of telescopes.

<> "I'm honored to answer for you, thank you for your patience, and find out for you: good Silao telescope ranges from 500 to 1000 yuan." Good binoculars are less than 500 yuan, cost-effective amateur astronomical telescopes are around 1000 yuan (online shopping), and a fully functional astronomical telescope is at least 100,000 yuan.

After all, if you have this heart, you don't have the financial ability to support such a luxurious hobby of yours. Now it is different from the advent of the "personal telescope", which can be used to observe the movements of many planets and various astronomical phenomena with a good split beam for a thousand dollars. There are even ** that can be purchased without 1000.

The first purpose of a telescope is to magnify the opening angles of distant objects, so that the human eye can see details with smaller angular distances. The second function of the telescope is to feed the beam of light collected by the objective lens that is much thicker than the diameter of the pupil (up to 8 mm) into the human eye, allowing the observer to see faint objects that were previously invisible. In 1608, Hans Lieberch, a Dutch optician, stumbled upon the idea that he could see in the distance with two lenses, and he built the first telescope in human history.

In 1609, Galileo Galilei, a native of Florence, Italy, invented the 40x double-mirror telescope, which was the first practical telescope to be put into scientific applications.
