How much do you know about the magnification of telescopes? What is a high-power telescope and what is an ordinary telescope? I'm afraid you only know the relationship between the numerical values. This article will introduce the variable-power high-power telescope in detail.
A telescope with a magnification of more than 10 times is called a high-power telescope, which is common knowledge about telescopes. So what we are talking about today is another thing. If a telescope reaches 60 times, what is the difference between it and the ordinary 10 times and 8 times through the naked eye? Why do we have to selectively purchase a 60-fold telescope to observe it?
It is well known that due to the distance, the objects that the human eye can see are only a detailed picture. If you want to observe the details, you need to use a telescope, and the distance between the naked eye and the object and the magnification of the telescope determine the scenery you see. For example, if you usually want to see something, you need to do three things: First, issue a command in your mind first, second, the brain responds to the command so that the head or the eyes can look straight at the object, and the third and most important point is that the eyes focus on the object so that a clear picture can be presented in front of you. The principle of telescope is the same, except that the panoramic picture is shrunk into the telescope tube, and then the reflection of the glass is realized, so the range of objects seen is naturally limited.
People say that everyone has his or her own specialty, and professional matters should be left to professionals. This principle also applies to the field of telescopes. Since there are conventional fixed-focus telescopes with 10x, 20x, or even 60x magnification, are there no telescopes that are as flexible as cameras? The answer is no, of course there are. In this ever-changing world, as people's quality of life improves, there is a type of telescope called variable magnification telescope in the field of telescopes that can fully meet the requirements of people in this area. Its name is BD80HD target telescope, which is a kind of high-power telescope.
The accessories of BD80HD target telescope include: nylon backpack, manual, lens belt, lens cleaning cloth, eyepiece cover, objective lens cover, camera tripod, but no tripod.
The high-power telescope of BD80HD target telescope has high-quality lenses that meet all different weather conditions. It is suitable for long-distance observation, such as bird watching and sightseeing. Waterproof, fog-proof, extra-large eyepiece, with hood. Large 80mm objective lens, high-magnification observation is possible even in low-light environments. 20 to 60 times 45° rotating continuous zoom, can clearly observe objects at different distances.
Retractable hood, easy to use. 360° lens body rotation, multi-angle observation of targets. Equipped with a standard tripod interface, it can be fixed on a tripod using a tripod adapter. Used with a digital camera bracket, it can be connected to most mainstream digital cameras or small video cameras.
