Things you do not know about telescopes

Telescope

The telescope is a kind of travel necessary items, but also for people to watch concerts and large sports games, I also like a telescope, and I also collect several different kinds of the telescope, but apexel telescope is a great telescope I have been using so far.  Today, I’m going to use my own experience to tell you what you do not know about telescopes.  

1. The basics of telescopes  

Telescopes are an astronomer’s best friend, with high magnification.  What’s more, a larger aperture gives a clearer, sharper, more detailed picture of the night sky.  Because the larger the aperture, the more light you can collect.

A telescope is an optical intensifier.  It is designed specifically for celestial observation (planets, stars, moons, and other distant celestial bodies).  The high magnification of telescope power allows for detailed observation.  Its larger aperture/larger lens collects more light, allowing us to see things even in low-light situations.  Telescopes are not easy to carry around because they are usually large and bulky.  Telescopes are expensive, but they are getting cheaper and cheaper.  

Telescopes are monoculars, which means they are made from just one eyepiece.  They observe distant objects, especially celestial bodies and mountains.  They’re heavy, so they’re mounted on a tripod.  Their telescopes can zoom from 12 or 15 times to 45 or 60 times.  The image seen with a telescope is on a plane and inverted.  Classical telescopes were designed primarily for astronomical observation.  They have higher magnification and larger apertures.  It allows them to view objects in low light conditions while allowing you to view darker objects in a more detailed way.  As a result, the telescope provides the best depth view and magnification.  

2. The relative brightness of the telescope  

The relative brightness (P) of the telescope is a theoretical value, which is related to optical coating, lens material, etc.  So p is equal to (D/M) ^2 is equal to D ^2.  Relative brightness is only a relative value, the comparison of size is only meaningful for the same brand with the same structure coating characteristics of the product, the different brand coating process is very different, and the actual brightness of the same relative brightness P is also very different.  

3. How does a telescope focus its wheel?  

The focus wheel see the smooth degree and precision of adjustment, to improve the handle, now many telescopes will do a bigger focus wheel, and take this as a booth, is more efficient to focus wheel to adjust, is advantageous for the single operation, and is convenient for fine adjustment, but also not only the most, too, must pursue adjust the length.  

The T01 wheel, for example, is about 17mm in diameter and can rotate 480 degrees, so the wheel linearly rotates 17mm * 4π➗ 3=71mm from 3m closest to infinity, which is a measurement of the wheel’s fine-tuning capability.  So big brand telescopes, even if the focusing wheel is relatively small, can also achieve good focus;  However, it is difficult to focus fine even if a major focusing wheel is used for off-brand products, because a large diameter does not mean a large rotation angle, and the maximum rotation Angle is rarely marked by the brand.

4. Don’t choose a telescope with too much zoom  

When we choose a telescope, do not choose a telescope with too large a zoom function, because such a telescope itself is prone to optical axis problems, may also have zoom synchronization problems, so it is very inconvenient to use, the actual use of the function is not good.  

Zoom telescopes are now very good for many people, but I do not recommend people to buy, them because the advantage of doubling is practical and convenient, but in this, the telescope has to pay the price of reduced optical effect, in the actual use of no benefit.  

5. Telescopes are not as powerful as possible  

The higher the telescope’s magnification, the larger the size of the image, but the greater the effect of turbulent atmosphere on objects.  Most laymen tend to try the maximum power of a telescope. The resulting image, though at high multiples, is blurry and irretrievable, and because of a flaw in the telescope’s design, the image cannot be retained in the telescope’s field of view.  So don’t go out and buy a high-powered telescope.
