The telescope looks at things that are reversed, how to repair

Common telescopes can be simply divided into Galilean telescopes, Kepler telescopes, and Newtonian telescopes. The telescope invented by Galileo occupies an important place in the history of human understanding of nature. It consists of a concave lens (eyepiece) and a convex lens (objective).

Its advantage is that it has a simple structure and can be directly formed into a positive image. However, since the invention of the Kepler telescope, this structure has not been used by professional-grade telescopes, but is mostly used by toy-grade telescopes, so it is also called a theater viewing scope.

Kepler telescope: The principle consists of two convex lenses. Because there is a real image between the two, the reticle can be easily installed, and various properties are excellent, so at present, military telescopes, small astronomical telescopes and other professional-grade telescopes are all using this structure.

Figure (2) Orthographic systems are divided into two categories: prism orthogonal systems and lens orthographic systems. Our common typical binoculars with wide front and narrow back use both a double right-angle prism orthographic system.

The advantage of such a system is that the optical axis is folded twice at the same time as the orthogram, which greatly reduces the volume and weight of the telescope. The lens orthodography system uses a complex set of lenses to invert the image, which is more expensive, but the Russian 20 50 three-section telescopic classical monocular adopts both a well-designed lens orthodoxy system. As shown in Figure (3).

Figure (3) Newton's invention of the reflecting telescope is mostly used in large base mirrors, so I will not repeat it here.

Turn the lens barrel 180 degrees and put it on!

Some people say: There is no way to do the opposite, the structure is like this, no one turns (people see) like a telescope!

What the telescope sees is the opposite! So what are you looking at from the other side of the telescope tube at 180 degrees? That is to say, you put the day on the ground, the earth on the day.

That is, what is the thing to see? In fact, it is the lens tube turned 180 degrees, and then installed! This refers to the one that is viewed from the side.

Softball bat telescopes don't work. Softball bat telescopes are also too tiring!

Regular telescope or astronomical telescope? It is very common for astronomical telescopes to have a reflective image, and if it is an ordinary telescope, there is a 45-degree reflector inside, which acts so that the image is positive, and you can check to see if there is something wrong with this reflector.

It's normal. To get the right image. Attach a positive image lens. Turn the telescope into rubber in reverse.

Either that, install a 45-degree steering prism.

Of course, the telescope sees things in reverse, and if you want to see the positive image, just install a positive image mirror and pull it.

Turn the lenses on the back and try again.

Everyone is really doing it, but there is no way to do it, the structure is like this, and you need to hurt your muscles and bones to come over.

Upstairs. You're so cute.

The better the quality of the mirror, the more light it absorbs, and the less likely it is to reflect it. Like Leupold's 59120 and Leupold

59125 has almost no light reflection under the illumination of light, and more than 95% of the light is absorbed. But mirrors aren't usually expensive. The average person can't afford it.

The reflection of the telescope will definitely be discovered, just like a glass placed under the sun, the reflection is obvious. I haven't heard of the solution, and I'm looking forward to ......

Today's telescopes are generally reflective and not easy to spot.

1 The old telescopes were coated with a red color film, which should be easy to spot if there was a light source in the field of vision, but the current telescopes are not easy to be found if they are blue or other coatings.

2 The reflection of a telescope is very small, it is different from the principle of a mirror, and it is also difficult to detect.

Solution: Avoid using the telescope under a light source.

If it is blurred, it means that the wipe is not clean. But from the experience of principle construction, it is generally not an eyepiece or an objective lens, unless he has touched these lenses.

A better telescope has the function of adjusting the difference between the left and right eyes, generally closing the right eye first, aiming the left eye at an object, adjusting the focal length, and then closing the left eye and aiming the right eye at the same object before.

At this time, do not move the big focus button, gently turn the small knob on the eyepiece of the right eyepiece, after it is clear, then the vision difference between the left and right eyes will be adjusted to the same distance, and then there will be no unclear vision or double vision and other adverse phenomena.

Summary. According to what you said, I guess that one of the four ridge mirrors of your telescope is dislocated in the middle of the fall, and the ridge mirror is pressed into the lens barrel with an elastic steel sheet, and the two ends of the elastic plate are fixed to the lens barrel with a small screw.

If you have the ability to do it, open the telescope tube and see if it is the best problem, and then re-fix the roof mirror, if the optical axis does not coincide, adjust the optical axis of the broken eye, and do not move the other eye.

When you open it, you can see the two screws facing the roof mirror, that is, adjust the two screws, try to keep them small and not move too much.

If you will get satisfactory results after careful adjustment, adjust it many times. Because your telescope magnification is a little higher, it is difficult to adjust.

How can I fix my telescope if I can't see clearly?

According to what you said, I guess that one of the four middle falls and dislocations of your telescope ridge mirror, and the ridge mirror is pressed into the lens barrel by a steel sheet with an elastic hand, and the two ends of the elastic piece are fixed on the lens barrel with a small screw.

If you have the ability to do it, open the telescope tube and then see if it is the problem, and then re-fix the roof mirror.

When you open it, you can see the two screws facing the roof mirror, that is, adjust the two screws, try to keep them small and not move too much.

Hope it helps you dear.

Summary. Hello dear, <>

If the lens is not damaged, the zoom can still use the telescope, and if there is a problem with these two items, it will be scrapped, and there is no shop to repair the telescope, and the after-sales service will not guarantee the broken one.

How to judge if the telescope is broken.

Hello dear, <>

If the lens is not damaged, the zoom can still use the telescope is fine, if there is a problem with these two items, then Biheng will be scrapped, and there is no shop to repair the jujube Huihuli telescope, and the after-sales service is not guaranteed for the broken. Stool informed.

Hello dear, <>

If your telescope has rubber skin, you can take it apart carefully, and you will see that there are 4-6 small screws in the mirror body. Then find a fixed telescope for the observation target and adjust the screws on the inside. It is a skillful screw that adjusts the prism, that is, the optical axis.

Start with one eye ** and focus until clear. Then use a small screwdriver to carefully tighten the prism screw, at this time the eyes can not leave the telescope, to always ** whether the target is ghosted, if the spacing of the ghost is large, it means that the screw is reversed, and the screw is screwed out. If there is still some ghosting, adjust the embedded screw on the inside of the other lens body according to the appeal procedure.

One thing to remember: if you find that the adjustment is reversed, you must remember how much the tightening or unscrewing is so that you can transfer it back in time. If it doesn't work, you need to adjust the screws on the goggle, generally the eyepiece has 3 screws, one of which is slightly larger and can't be moved, which is to fix the eyepiece.

To be tuned are two small screws.

How to tell if an astronomical telescope is damaged.

Hello dear, <>

Kiss your side, try to use it normally to see if the lens is damaged or if it can be focused.

Will the rusty Screws of the New Tran 80 DX have an effect?

Hello dear, <>

Will the rusty 80 DX screws of the new special wheel Sun Lang have an effect? Zhaolian will not affect the use, the bolt just plays the role of Tong Chong to fix the hardware, as long as it can be fixed.

I was 60 24 and was also dismissed by my classmates.

Gently wipe off dirt from the mirror with high-purity alcohol.

30x35 Looking at the parameters, it should be a counterfeit product with random labels, buy a regular one.

There are two types of telescopes:

1.Refracting telescopes (e.g., Kepler).

2.Newtonian reflective telescope.

Looking at the optical path diagram below, it can be seen that 1The lenses of the Zhensun type telescope are all lenses, and these two lenses turn the image upside down and left and right twice, so that it becomes a positive image again.

2.In the reflective type of telescope, the image is turned upside down by a concave lens for the first time, and the image is reversed from the left and right, and the second time the image is reflected by a plane mirror, but it does not become positive, and a device is added to make it positive.

Therefore, the inverted image of the telespectacle will become positive when reflected by the convex lens, and the reflection through the plane mirror will not become positive.

Adding a right-angled prism to the optical path of the telescope can turn the image upside down, as shown in the figure: ordinary binoculars are this kind of structure, but there are two, one is used to change the horizontal direction of light, and the other is used to change the vertical direction, so the shape of ordinary binoculars is not a straight cylinder but a turn.
