Anonymous users2024-02-06There are three types of astronomical telescopes: refractive, reflective, and reentent. Among them, the achromatic refractive telescope under the refractive classification is more suitable for family and personal entry.
In achromatic refractive telescopes, there are also different price points:
Below 500 yuan (it is a toy, it is extremely not recommended to buy), which means 60az, Boguan 70400 and so on.
500-1000 yuan (you can look at the moon, Jupiter, Saturn, etc., but the caliber is small, so you can't observe nebulae, galaxies and other deep-sky objects (too dark)). There are 80EQ, 90EQ, etc., and the ultimate magnification of this type of telescope is about 120-150 times, and then it will be blurred.
Don't believe the advertisements and **!!
Visual renderings: Jupiter (around 140x):
Saturn (around 140x):
Moon (about 50 times):
The next price: 1500 yuan - 2500 yuan, the recommended telescope at this price is the Sky Wolf Painter series. Telescopes at this price range are better than the previous price in terms of optical performance and bracket stability. Visual Effect:
Jupiter: Saturn:
Moon: When you have a budget of more than 3,000 yuan, it is not recommended to buy an achromatic telescope, and the more cost-effective one at this price is the Newtonian reflecting telescope (referred to as bull reversal). Because of its larger aperture, the cow can see brighter images and have a higher resolution.
The bull anti-brand recommends Xinda (also known as Xingda), whose primary mirror is parabolic, and the imaging effect is better than that of Phoenix, Boguan and Xingtrang.
Of course, a retractable telescope is also a good option, but it is slightly less cost-effective.
There is another category in the refraction type: apochromatic (abbreviated as APO), because of its excellent optical quality, ** is also very expensive, the cheapest is also more than 3000 yuan, suitable for more wealthy families.
To borrow the words of the predecessors: "The quality of the equipment depends not only on the equipment, but also on the people." The quality of a piece of equipment also depends on the skills and expectations of the user.
Hopefully, the work I spent an hour on will solve your queries.

Anonymous users2024-02-04People often ask how many times the magnification of the telescope is, and the magnification is used as the main indicator, believing that the larger the magnification, the better. In fact, the magnification of the telescope does not represent the quality of the telescope, let alone the higher the better. The actual practical magnification is about 2 times the effective clear aperture (mm) of the telescope objective, for example, about 160 times for an 80mm telescope.
Beyond this practical magnification, the quality of the imaging begins to gradually decline. The ultimate imaging magnification can only be about 3 times the effective clear aperture (mm) of the telescope objective, for example, the ultimate magnification of the 80mm aperture telescope is about 240 times, and the imaging quality will plummet until it is not imaged. Even if the telescope has a large enough aperture, the ultra-high magnification magnification magnified the image and the jitter of the atmosphere is magnified and cannot be observed.
If you see a mark in the market.
There may only be two telescopes that are five or six hundred times or even nearly a thousand times: the manufacturer's false standard magnification or the theoretical magnification that cannot be observed at all, you had better turn around and leave, because such manufacturers and merchants are not deceitful and irresponsible to consumers.

Anonymous users2024-02-03Summary. The Cintron 80DX is officially equipped with 20mm, 10mm, 4mm eyepieces and 3x extenders, and the 90DX is officially equipped with 32mm, 23mm, and 10mm eyepieces, excluding extenders. In actual observation, the observation of celestial bodies near the zenith is generally relatively rare, so the 90dx is only equipped with a 45-degree zenith mirror, and the angle of the eyepiece is more appropriate for daily observation, and the observation experience will be better; The 80DX is equipped with a more common 90-degree zenith mirror, which is obviously not convenient enough for observation, and the observation experience is slightly worse.
The price of the Xingtran 80DX astronomical telescope is about 1100 yuan, with high magnification and rich magnification, for entry-level astronomy enthusiasts, 80DX is more cost-effective. The price of 90DX is about 2000 yuan, and the official eyepiece magnification is low, but most merchants will give away 5x extenders, which can be used together to achieve a relatively high magnification; Coupled with accessories such as the 90DX's auto-tracking motor for continuous, detailed observations of the planets, the 90DX is more suitable for advanced astronomy enthusiasts.
I bought the Cintron 80DX model, it cost 1100, you can also buy the Centron 90DX price between 1900 and 2000, sorry, please talk about it in more detail?
The Cintron 80DX is officially equipped with 20mm, 10mm, 4mm eyepieces and 3x extenders, and the 90DX is officially equipped with 32mm, 23mm, and 10mm eyepiece wheels. In actual observation, the observation of celestial bodies near the zenith is generally relatively rare, so the 90dx is only equipped with a 45-degree zenith mirror, and the angle of the eyepiece is more appropriate for daily observation, and the observation experience will be better; The 80DX is equipped with a more common 90-degree zenith mirror, which is obviously not convenient enough for observation, and the observation experience is slightly worse. The price of the Xingtran 80DX astronomical telescope is about 1100 yuan, with high magnification and rich magnification, for entry-level astronomy enthusiasts, 80DX is more cost-effective.
The price of 90DX is about 2000 yuan, and the official eyepiece magnification is low, but most merchants in Hengwu will give away 5x magnification, which can be used together to achieve a relatively high magnification; In addition, the 90DX is more suitable for advanced astronomy enthusiasts because accessories such as the 90DX auto-tracking motor are conducive to continuous and detailed observation of the planets.

Anonymous users2024-02-02Summary. Hello! We're happy to answer for you!
Non-professional astronomical telescopes can be divided into several broad categories: reflective telescopes, refracting telescopes, and medium-aperture telescopes. Among them, the reflecting telescope is the easiest to operate, has the widest range of application, and is suitable for household use.
Even beginners can quickly master how to use it.
Hello! We're happy to answer for you! Non-professional astronomical telescopes can be divided into several broad categories:
Reflecting telescopes, refracting telescopes, and medium-aperture telescopes. Among them, the reflecting telescope is the easiest to operate, with the widest range of application, suitable for household use. Even beginners can quickly master the techniques used by Hu Zheng.
Extended Oak Sedan Branch Content: Due to the simple optical structure of the anti-sail guessing telescope, with clear images, and low cost, it is more suitable for domestic telescopes than other types of astronomical telescopes.
How big is it to buy at that trail.
Is the brand of Xingtron good?
This is an old brand, and the price and function are very high, which can be considered.
How big is the diameter of the mouth to buy.
Hello! I recommend that you choose a telescope with a diameter of 80-150mm, which can observe most of the astronomical scenes such as colored planets, star clusters, star clusters, and subtle light changes at night, which is more suitable for non-professional telescopes at home.
If you get started, 80pro is better or 130eq.
80pro is good if you get started.

Anonymous users2024-02-01A home astronomical telescope MEADE (Meade) is better.
Founded in 1972 and owned by Meade Instrument Inc., Meade is one of the world's largest manufacturers of telescopes, known for manufacturing optical and optoelectronic instruments such as consumer telescopes, binoculars, microscopes, CCD cameras and telescope accessories.
How to buy a home astronomical telescope:
1. Be careful that the principle of the solar astronomical telescope is similar to that of a magnifying glass, some people do experiments to put the pig's eye on the lens and aim at the sun, and it will be ** in less than three seconds.
2. Be careful with the equipment. Even if it is a portable telescope, there is also a lens tube, which is a fragile and precise lens, not fitness equipment, handle it gently when you move it, don't pick it up and drop it You say this is not your mirror? Ah, that's fine.
3. Be careful with the weather. We all know that it is good to observe astronomy on the beach and in the mountains, but the elementary school geography teacher said that you are not afraid of thunder when you stay here, so you can do it yourself, and you can withdraw when you see a cloudy day. <>
First of all, you have to know what you want to see, the planet Deep Space Hoshino? >>>More
It's not high, if it weren't for his automatic star search, it would be equivalent to a telescope of 500 yuan. Automatic star hunting isn't very useful, unless you're the kind of enthusiast who uses tens of thousands of dollars of equipment to shoot galaxies and nebulae all night. Every time you go downstairs for astronomical observation, holding a telescope for automatic star searching, you need to spend dozens of minutes to enter the time, enter the coordinates, align the north, horizontal placement, N star calibration and other complicated steps, in order to automatically find the star, and this low-end automatic star search theodolite accuracy is often very low, sometimes the automatic star search is not accurate. >>>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! Break a leg!
I said, don't you want your own eyes, as long as the telescope is not standardized, the impact on the eyesight is great, not to mention the astronomical telescope, I advise you to buy a regular one, you can go to Wuhan Rongcheng Technology that telescope ** to see, how to say that it is still the most important thing in your body, not to mention whether there are materials, and the materials are not standardized, it is very difficult to make alone, it is a fine job, otherwise why would the telescope sell so expensive.
A large-aperture convex lens (with a long focal length) is used as the objective, and a shorter focal length (the shorter the better) is used as the eyepiece. If you want to multiply, put a concave lens between the eyepiece and the objective.
