The main purpose of monocular high power telescope and binocular high power telescope

In fact, the reasonable multiple of the telescope is related to the aperture of the telescope and the observation method: if the aperture is large, the multiple can be appropriately high, and if the telescope is fixed with a tripod, it can be higher than the handheld observation. If you choose hand-held binoculars for observation, 7-10 times is sufficient, and the maximum should not exceed 12 times. Otherwise, the higher the multiple of the observation field, the smaller and darker the observation field, and the observation effect will be reduced. In particular, the jitter caused by high power will greatly increase, making the observed scenes unable to be stable and difficult to observe normally.

In theory, the magnification of a telescope is inversely proportional to the field of view of the telescope. The higher the multiple, the smaller the field of view. Therefore, the multiple of the telescope should not be too large. If the aperture of a 50mm binocular telescope reaches 20 times, it basically reaches its limit. If the multiple is large, the field of view will be too small. The following is a summary of astronomical telescope manufacturers' experience in the telescope industry!

First of all, binoculars have a strong sense of three-dimensionality, because when the binoculars are used at the same time, the binoculars will be clearer and more comfortable to use. Binocular high-power telescopes are mainly used for scenic viewing, forest fire prevention, border guard posts, grass grazing, family star watching, high-rise office viewing platforms, power inspections, etc. Here I am more familiar with cost performance, according to a reference in use:

1. Sightseeing telescope;

Generally speaking, scanning telescopes and coin-operated telescopes have been widely used in scenic spots. After all, in addition to giving visitors a different visual experience, earning a small amount of operating expenses is also a win-win situation.

Yj-3 coin-operated telescope is a coin-operated telescope specially designed for scenic spots. It can fully meet the needs of tourists for long-distance viewing and is suitable for non-professionals (tourists) to use frequently. Yj-3 coin-operated binoculars can work in different climatic environments and can adapt to the ever-changing outdoor environment. Its advantages of simple operation performance, excellent optical performance, stable electrical performance, solid structural performance, novel appearance design, and super high cost performance have become the first choice for many scenic spots.

2. Forest fire prevention and border defense;

In this regard, the astronomical telescope lens can see farther, wider, and more detailed. The sentry mirror of the observation telescope is a precision optical instrument that can change the magnification, and is suitable for long-distance observation under various climatic conditions. It can also measure the distance, height, and angle between two targets. When observing various targets, it has a clear, comfortable, real, and three-dimensional feeling. The telescope has a refractive adjustment mechanism, which can conveniently meet the requirements of people with different eyesight and pupil distances to observe objects at different distances.
