What does a 30x60x80 telescope mean? Urgent! Urgent! Urgent! How does it look like the view? Is it c

There is no such specification at all, and there is no such standard.

Regarding the callout, I'll give you an example, 8x26 means 8 times with a caliber of 26 mm.

However, it is important to note that this method of reading numbers is not always useful! This one, like the one you asked, is a typical example. Because there are many fake telescopes now, there are all kinds of false propaganda, such as "night vision", "infrared", "Japanese cherry blossoms", "Russia", etc., many of them are indiscriminately marked such as 30x60, or 50x9999, and so on.

They are all random labels, not only can not be used as the basis for normal interpretation, but are flaws in judging counterfeit products.

Like the 30x60x80 you asked, you also understand what you said above, and you can't decipher it at all. It is recommended that you understand the basics first.

Particular attention is paid to the issues related to multiples, military, night vision, etc., that is, the introduction of some common false propaganda. Pay attention to identification.

If you haven't bought it yet, don't choose this one. If you've already bought it... Don't be too sad, there are indeed too many fakes now, and many, many people have suffered this loss, the first time, it can be regarded as normal.

It seems that there is no telescope with such specifications, if you want to buy a good telescope, such as 20x80, 25x100, etc., it is recommended to take a look at the Yuanda brand telescope in ****, the Yuanda brand telescope is the independent brand of Yuanda Optics. Yuanda Optics is a military telescope production base, and it is also the only enterprise in China that has passed the appraisal of the Ministry of Science and Technology of Ordnance Industry Group and can be exported to foreign military markets. Now in order to meet the needs of domestic enthusiasts, launch their own brand.

Yuanda brand telescope is 10-year warranty, with an officially authorized warranty certificate and an official seal of 10-year warranty. Yuanda's military telescope has passed the US military standard. From a few hundred dollars to a few thousand dollars, I wish you can find the right telescope for you!

50 is the aperture of the objective lens in millimeters. 22 is the magnification of the telescope.

1. According to the literal hard interpretation, it is 50 times, the aperture is 50 mm, and it is impossible for a hand-held telescope to have such specifications. Therefore, this is not a formal and true mark, and it cannot be interpreted normally.

2. Choosing reasonable specifications, it is complicated to say, in fact, it is very simple, that is, do not be greedy, many misleading and deceitful businesses, in fact, the government uses consumers' greed for multiples and other aspects (human nature, but unfortunately human nature is often used to make traps) to achieve the goal of sensitive and fierce.

3. Be sure to choose normal, formal and professional products, don't choose the kind of exaggerated. I feel that you can bridge the crack can still lack a systematic understanding of the telescope, you can take a look at popular optics, there are some basic knowledge introductions, more comprehensive.

At present, basically every type of telescope will be marked with a specific magnification and aperture, 40 60 usually means that the telescope contains a multiple of 40 times, and the aperture of the objective lens is 60 mm.

40x60 is a standard marking method for telescope specifications, and its format is generally [multiple of the telescope objective lens aperture (mm)], which is an important indicator when selecting a telescope. In addition to the lead state, the telescope may also be marked with a field of view [n 1000 m], which means that an object n far away can be placed into the field of view at a distance of 1000 meters.

In addition to this, common parameters of the telescope include the diameter of the exit pupil, resolution, twilight coefficient, light gathering power, etc.

The field of view is 1000 meters, and the magnification is 20 times.

When people buy a telescope, it is common to see several Arabic numerals on their price list.

Let me give you an example. For example, it is marked with 10 50 mm 5°, which means that it has a diameter of 50 mm and a field of view of 5 degrees (i.e. at 1000). Some people may think that the higher the number of technical parameters, the better, but this is not the case.

The magnification is inversely proportional to the width of the field of view, i.e., the greater the magnification, the smaller the width of the field of view, which is not conducive to searching. The larger the diameter of the objective lens, the more light intake, and the stronger the resolution ability when the light is insufficient, but this will inevitably lead to an increase in the volume of the telescope, which is not conducive to carrying. You may feel at a loss for what to do, but if you can learn from each other's strengths, you can also buy a telescope that you like.

Limit magnification (limit magnification affects the maximum effective magnification that the telescope can get). Generally 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.

It is important to note that the magnification of the telescope is not always better. Once the magnification exceeds the limit magnification of the telescope (effective magnification), the image quality will be blurred and details will be lost due to invalid magnification.

The parameter x60 indicates that the magnification of the telescope lens is 40 times, and the diameter of the objective lens is 60mm.

2. There are many things that are more important than multiples when choosing a telescope, such as the diameter of the exit pupil and the field of view. Multiples are not the only criterion. Because if the magnification exceeds the standard allowed by the telescope specifications, the clarity of the clear finger will decrease.

For example, for a telescope with an objective lens diameter of 50 mm, the magnification should not exceed 50 times. In fact, a telescope of about 10 times is enough for most of our requirements.

3. The distance seen through the telescope is related to people's eyesight.

4. The distance seen by the telescope is related to the size of the object.

5. The distance seen by the telescope is related to the air quality.

6. The distance seen by the telescope is related to the quality of the telescope itself.

Me, amateur.

20x50 in front of 20 refers to 20x magnification.

The back 50 refers to the diameter of the telescope objective lens 50mm

Looking at 1000 feet away, the view is 168ft in diameter and how big a circular 168ft is, I don't know yet.

20 is its objective magnification, 50 is the aperture, and 20x50 is the magnification.

20x50 on the telescope, this is how magnified it is.

20x magnification, 50mm caliber.

1. The magnification is too large and should not be stable.

12 times is the hand-held limit, and it is best to have your elbow supported when observing, and the body or telescope is attached to some fixed object.

2. If the magnification is large, the actual field of view will be reduced accordingly.

In general, the larger the multiplier, the smaller the area that can be observed at the same time.

3. In the case of the same objective lens aperture, the larger the magnification, the lower the inverse square ratio of brightness.

4. The acquisition of large multiples is generally carried out through the eyepiece with a short focal length.

5. The unsatisfactory observation conditions such as the atmosphere itself also limit the maximum magnification.

780 yuan or so.
