How about a telescope 20x25? 30x40, that s better

In fact, choosing a reasonable specification is complicated to say, in fact, it is very simple, that is, don't be greedy, many misleading and deceitful businesses, in fact, are using consumers' greed for multiples and other aspects (human nature, but unfortunately human nature is often used as a trap) to achieve the goal.

And depending on the two specifications you asked, there are actually a lot of questions in them. It is impossible for a hand-held telescope to have such specifications, it is all random marking. That is, the specification of this product is not true.

You ask both of these are, like what 30x40, the most common deceptive specs too.

In fact, there are some things that you don't need to ask like this, there are some very basic knowledge aspects, if you understand a little bit, you will judge yourself.

Each article is a common misleading introduction, so it is recommended not to rush to start and understand it systematically.

There are a lot of fake and inferior products on the market now. Be sure to choose normal, formal and professional products, don't choose the kind of exaggerated.

None of them are good. The exit pupil must be at least equal to or greater than 4 mm, otherwise it cannot be held in the hand, and the image cannot be seen clearly. Exit pupil size = telescope aperture magnification.

Choose 10x50, 10 is a multiple of a hand-held telescope, basically between 7 and 10, and more than 10 basically need tripod support.

Generally speaking, we believe that the limit magnification is 2 times the aperture of the telescope, for example: the limit magnification of the 102 1000 model telescope is 200 times, but this is only theoretically speaking, there are differences in optical quality between different brands of telescopes of the same model, and a telescope with excellent optics can exceed the limit magnification by about 50 times.

Exit pupil diameter: is a parameter that roughly describes the brightness of the image. In low-light environments, the larger the diameter of the exit pupil, the clearer the image.

The maximum human pupil, under normal physiological circumstances, will not exceed 7mm, so the diameter of the exit pupil greater than 7mm is inadvertently a waste of light. This parameter does not fully reflect the quality of the telescope.

Because of this parameter, as long as it meets the manufacturing specifications, the numerical requirements can be met. The larger the diameter of the exit pupil, the more suitable it is for use in bumpy environments, and the more stable the observation picture will be, so telescopes such as 7x50 are mostly suitable for use at sea.

This value can be calculated by dividing the objective diameter by the magnification.

Summary. Of course, the 60 60 model of the telescope is better, because it has a higher magnification and can be observed at a greater distance.

Extended Content: What does telescope 20x50 mean? I believe that many people don't know about this, and the specific answers are as follows:

When people buy a telescope, it is common for them to have several Arabic numerals on their price lists, and these numbers have corresponding technical parameters. For example, if it is marked 10 50 mm 5°, it means that the diameter of the objective lens is 50 mm and the field of view is 5 degrees.

The magnification is inversely proportional to the width of the field of view, i.e., the larger the magnification and the smaller the width of the field of view, the less favorable it is for searching. The larger the diameter of the objective lens and the more light intake, the stronger the resolution ability in low light, but this will inevitably lead to the increase in the volume of the telescope, which is not conducive to carrying.

20 in the telescope 20x50 indicates the close-in multiple, and 50 indicates the objective aperture of 50mm.

Which is better, telescopes 60 60 or 20x50?

Hello, I'm glad to be able to answer your questions for you, please wait for two minutes, I see your question here, and I'm going to inquire about the relevant information for you, the teacher also needs time to type, please be patient and wait for two minutes! Please don't end the consultation|! <

I believe that many people do not understand this, and the specific answer is as follows: when people buy telescopes, they often have several Arabic numerals on their price lists, and these numbers have corresponding technical parameters. For example:

Marked with 10 50 mm 5° means that the diameter of its objective lens is 50 mm and the field of view is 5 degrees. The magnification is inversely proportional to the width of the field of view, i.e., the larger the magnification and the smaller the width of the field of view, the less favorable it is for searching. The larger the diameter of the objective lens and the more light intake, the stronger the resolution ability in low light, but this will inevitably lead to the increase in the volume of the telescope, which is not conducive to carrying.

20 in the telescope 20x50 indicates the close-in multiple, and 50 indicates the objective aperture of 50mm.

Summary. 10x50 good. Both of these telescopes have a diameter of 50mm, the former one is 20 times, and the latter one is 10 30 times, which can be zoomed, generally speaking, the imaging effect of the zoom telescope is not as clear as that of a telescope with fixed magnification, so the former one will be better.

But the magnification of 20 times binoculars is too high, it is better to have a tripod to observe, if you are handheld, it is recommended to buy a 10 times telescope, with an aperture of 30 50mm. The binoculars in your hand should be less than 10 times less than to see the scenery so as not to get dizzy.

10x50 good.

10x50 good. The aperture of these two telescopes is 50mm, the former one is 20 times, the latter one is 10 30 times, can be zoomed, generally speaking, the imaging effect of the telescope with the magnification is not as clear as the telescope with fixed magnification, so the former one will be better. But the magnification of the 20 times binoculars is too high, and it is better to observe if you have a tripod on the land, if you are handheld, it is recommended to buy a 10 times telescope, with a diameter of 30 to 50mm.

The binoculars in your hand should be less than 10 times less than to see the scenery so as not to get dizzy.

The difference between the two is the difference in magnification, the former is 10 times, and the latter is 20 times. If the specifications are possible, the general telescope can also be magnified by 20 or 10 times. It is important to note that:

The magnification of the telescope is not the bigger the better! Once the magnification exceeds the limit magnification of the telescope, the image quality will be blurred and the details will be lost due to invalid magnification.

Hello, it is a pleasure to serve you and give you the following answer: The difference between 10x50 and 12x50 telescopes is the magnification and the size of the eyepiece aperture. The magnification of the 10x50 telescope is 10x, and the eyepiece aperture is 50 mm; The magnification of the 12x50 telescope is 12x, and the eyepiece aperture is 50 mm.

The advantages of a 10x50 telescope are: it has a lower magnification, which can provide a larger field of view and make it easier to see more sights; It has a larger eyepiece aperture that collects more light and makes the field of view clearer. The advantages of a 12x50 telescope are:

It has a higher magnification, which can provide a clearer field of view and make it easier to observe more details; It has a larger eyepiece aperture that collects more light and makes the field of view clearer. Therefore, the choice of 10x50 and 12x50 telescopes depends on your observation needs. If you need a larger field of view and it's easier to see more, then a 10x50 telescope is better for you; If you need a clearer field of vision and it's easier to see more detail, then a 12x50 telescope is more suitable for you.

Steps to use the telescope:1Mounts the telescope on a tripod to ensure that the telescope is stable on the ground.

2.Point the telescope at the object you want to observe, then adjust the focal length of the telescope so that the object is clearly visible. 3.

Enlarge the eyepiece aperture to its maximum in order to collect more light and make the field of view clearer. 4.Adjust the magnification of the telescope to the magnification you need to make it easier to see more sights or details.

5.Focus the telescope.
