The multiplier is eight times, the caliber is 30 mm, the caliber is on the small side, and the caliber is recommended to be more than 42.
A telescope is an optical instrument that uses lenses or mirrors and other optical devices to observe distant objects. Utilizes the refraction of light through a lens or the light being concave.
The reflection causes it to enter the aperture and converge for imagery, which is then seen through a magnifying eyepiece. Also known as "clairvoyant mirror". The first role of a telescope is to magnify the opening angle of a distant object.
Enables the human eye to see details with smaller angular spacing. 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.
After nearly 400 years of development, telescopes have become more and more powerful, and the distance of observation has become farther and farther. Galileo Galilei, a native of Florence, Italy, in 1609.
The 40x double mirror was invented.
Telescope, the first practical telescope to be put into scientific use.

If the binoculars you are talking about are available on the market, then you can know from the parameters that this should be a typical virtual standard product. 80*160, which means that the magnification is 80 times and the diameter is 160 mm. You must know that the large coin-operated double cylinders fixed on the high-altitude observation deck have a diameter of only 60 100mm and a magnification of 15 40 times.
135m 1000m means that its viewing angle (field of view) can cover 135 meters horizontally at a distance of 1000 meters, that is, degrees. Converted to the eyepiece angle of view, i.e., degrees, is equivalent to the angle of nearly two rotations. Can you imagine?
To see the full field of view of this telescope, you have to rotate your eyes sideways for a circle and a half. Finally, telescopes do not have such an indicator as "how far they can see". Anyone who uses this indicator to promote products is either a fool or a **.

Both 7x50 and 10x50 binoculars are quite sleepy and excellent products, but they serve different purposes. The 7x50 binoculars have a larger field of view, which is suitable for long-distance observation and positioning, such as stargazing, navigation, shooting, etc. The 10x50 binoculars have a higher magnification for a clearer field of view, which is suitable for close-up observation, such as field observation, wildlife observation, etc.
In general, both 7x50 and 10x50 binoculars have their own advantages, and the choice should be based on your needs.

The telescope 7x50 is better. The 7x50 telescope is a low-light marine stargazing type, which is very comfortable for observation, good imaging stability, and high brightness in low-light environment, but the volume and weight are too large, and it is not suitable for general daily use. The 10x50 telescope is a balcony type, which has high specifications and high brightness, but the imaging is slightly returned with jitter, and it is necessary to find objects to lean on the leaky chain when observing, and the volume and weight are large, which is not suitable for outdoor use.
If you are a hobbyist, you can choose a professional configuration of 7x50.
The higher the magnification, the smaller the field of view, the lower the brightness, and the more shaky, the worse the comfort. At present, the magnification of hand-held binoculars is mostly multipliers, while 8 times is the mainstream, and 6 times is almost no such style.
Considerations for choosing a telescope.
When choosing a telescope, it is necessary to pay attention to knowing the purpose of the telescope in advance: whether it is to watch a performance competition, or outdoor hiking, or bird and star watching, or balcony viewing, different uses have different requirements for the volume and weight multiple of the telescope. The astronomical telescope choice is that the larger the aperture, the better, and the heavier the equatorial mount, the better.
Novices with average conditions should choose an 80 refractor or a 150F5 N reflex telescope. Enthusiasts with a higher budget can try to choose a telescope with a larger head and better optics.

Hello personal guess Min thinks that 10 50 good 7x50 can appear larger picture, higher wide angle, which is of great help to the observation of stars, the advantage is that the flood effect is better, the disadvantage is that the resolution is lower, and the magnification is lower. 10x50 conditions can be very good, and with good resolution and visibility, you can see distant targets more clearly, but the field of view is narrow, and the bloom effect is poor, which may not be suitable for stargazing. Overall, the 7x50 is great for outdoor field practice and stargazing, while the 10x50 is more suitable for more hands-on use, such as long-range target boom effects or tours.

Generally, 8x40 is better. But if you want to choose according to your needs, there is no light pollution.
The difference is that the magnification is different, 7 50 generations of loss table 350 times magnification, 10 50 represents 500 times magnification. A telescope is an optical instrument that uses optical devices such as lenses or mirrors to observe distant objects.

Hello dear, glad to answer for you. 1. The telescope 7x50 is better The x50 telescope is a low-light marine type stargazing type, which is very comfortable for observation, good imaging stability, and high brightness in a low-light environment, but the volume and weight are too large, and it is not suitable for general daily use. 3. The 10x50 telescope is a balcony type, which has high specifications and high brightness, but the imaging is slightly shaky, and it is necessary to find objects to lean on when observing, and the volume and weight are large, which is not suitable for outdoor use.
4. If you are a hobbyist, you can choose a professional configuration of 7x50.

This is equivalent to asking: is it better to have a sedan or an SUV? Is it better to have a pistol or a rifle?
The two mirror sizes in your question vary greatly in weight and performance, and they are suitable for different scenarios. If you want to compare whether they are good or not, you can set up a scenario: for example, if you go on a hike, a bright, clear and high-magnification 10x50 mirror weighs about 1 kilogram, while an 8x30 mirror with a slightly darker image weighs only 300 grams of dust.
