I want to buy an astronomical telescope that can be connected to a computer to take pictures.

It is important to know that astrophotography with a telescope is never a matter of clicking on the eyepiece. The first way to shoot is to use a CCD or SLR to unscrew the lens and connect it to Tianwang, and then shoot a single frame or **, and carry out various post-processing on the computer.

Therefore, LZ should be familiar with the optical structure of Tianwang, and then be able to use the operation software and some functions of the superposition software and PS, and also have some understanding of the interface on the computer.

In this way, LZ can safely buy mirrors for planetary photography. If you want a good effect, it is best to use the big Shika of Xingtron or Mead, followed by the 150 maca of Boguan or Xinda, and then the second is the small black of Xinda plus a little heel. In terms of photography, if LZ has a DSLR, it can be used, as long as it is equipped with the corresponding brand of adapter.

But a dedicated astronomy camera is better. For example, ASI120MM, ASI120MC, QHY5-II, etc.

At the same time, LZ is welcome to come to the astronomical bar to communicate.

The resolution of astronomical photography is very demanding, and astronomical telescopes that can be connected to a computer to take pictures may be very expensive.

Connect the SLR to the telescope, and then to the computer.

Here's how:

2. Put the eyepiece into the bayonet and lock it, and loosen the screws that adjust the bayonet up and down. Turn the camera on and use the zoom button to focus the lens.

Adjust to the maximum, then put the camera on the stand to adjust the distance between the camera and the eyepiece, aim the camera lens at the center of the eyepiece, and after seeing a circular bright circle from the camera screen, lock the camera attachment screws, and lock the screws that adjust the bayonet up and down. As shown in Fig

3. After connecting the camera, point the telescope at the target to be observed. From the finderscope** target, adjust the telescope so that the target is in the center of the field of view. Then, turn the telescope's focus knob to focus.

4. This is a regular digital camera.

Here's how:

1. The main functional structure of DCA is shown in the figure, with an eyepiece mount; bayonet locking screws; bearing focusing screws; Camera attachment screws. As a special note, the eyepiece diameter of astronomical telescopes generally comes in two sizes: and, also called small eyepiece and large eyepiece.

2. Put the eyepiece into the bayonet and lock it tightly, and loosen the screws that adjust the bayonet up and down. Turn the camera on, use the zoom button to adjust the focal length of the lens to the maximum, then put the camera on the stand to adjust the distance between the camera and the eyepiece, aim the camera lens at the center of the eyepiece, and after seeing a circular bright circle from the camera screen, lock the camera connection screws tightly, and lock the screws that adjust the bayonet up and down. As shown in Fig

3. After connecting the camera, point the telescope at the target to be observed. From the finderscope** target, adjust the telescope so that the target is in the center of the field of view. Then, turn the telescope's focus knob to focus.

Take off the eyepiece, install the SLR mount (if the standard configuration is not available, you can go to the ** to find it, usually the T mount), and then connect the SLR, with M file.

There is only one kind of press ring, which does not recognize any AI or F, because the astronomical telescope camera only has the function of manual shooting; In addition, the eyepiece on the telescope must be removed to attach the adapter ring, and the eyepiece at this time is the camera viewfinder.

Generally, there are professional adapters, which are selected according to the caliber of the lens.

**There are joints sold on the Internet, as long as you look at the model.

Telescopes play an extremely important role in astronomical observations, and naturally with proper movement, they can achieve results that are incomparable to other methods in astrophotography.

The most famous and extreme example, that is, Hubble, Hubble has been in the sky for 25 years, using the caliber of meters and the conditions without atmospheric interference, as well as the advantage of being able to take a long time, so that human cognition of the starry sky has reached a great level. Of course, there were also many beautiful ** photographs (largely to please the public, to gain support, and finally to get funding), one of the most famous examples, the creation pillar of the Eagle Nebula (M17):

However, the ruler is short, the inch is long, and the telescope has a huge disadvantage, the field of view is very small, from an aesthetic point of view, so it is generally used to photograph planets, comets, binary stars and deep-sky objects.

Small telescope photograph of Jupiter.

Comet Hale-Popper.

The Great Andromeda Nebula (M31, which is actually a galaxy larger than the Milky Way).

The above works can be photographed by small telescopes. However, the image quality of Jupiter is relatively poor, and it is necessary to explain to novices not to expect too much from the photographic effect, especially beginners. I can almost guarantee that even the first image will not be able to achieve the results of the first image within a few months of contact.

Since you said what you can shoot, let's talk about whether it is not suitable for shooting. That's astrophotography that requires a wide perspective, such as the Milky Way, star trails, or meteors. It's not that telescopes can't photograph these, it's just that these things are hard to find in telescopes, and even if they are forcibly photographed (for example, by a meteor passing by), they have little aesthetic value.

Play photography poor three generations, play astrophotography ......Anyway, it takes more time and money than just photography. In addition to the necessary camera, if you want to use a telescope for astrophotography, if you want to photograph celestial objects other than the moon, you will theoretically need at least a single axis (in fact, they are all equipped with a double axis heel, unless you can ensure that the polar axis is adjusted correctly). And shooting in the suburbs far away from the city, a **takes at least a few minutes** (that M31 accumulates at least ** a few hours), whether it is difficulty or the sacrifice made, it is difficult for dragonflies to accept.

There are about 2 types of equipment for telescopes and mirrors!

In the case of a mirror! 2 ways to access shooting!

1.Tianwang + notebook + camera.

2.Telescope + SLR camera + adapter ring**The adapter is something used to connect a DSLR camera to a mirror).

Another is an ordinary digital camera for home use + a universal shooting stand.

There are special interfaces on astronomical telescopes.

No astronomical telescope can be directly connected to the SLR mount, and the corresponding reporter is installed.

Don't listen to the telescopes, 80% of the telescopes take very poor astronomical photos.

Only 600mm fixed focal head can be burned.

Nikon itself is a telescope, you can check it on Nikon's official website.

can be used on SLR.

Buying a home astronomical telescope requires the following steps: Elimination.

1.Determine the budget: The home astronomical telescope ranges from a few hundred yuan to thousands of yuan, and you need to choose according to your budget range.

2.Learn about telescope types: Home astronomical telescopes are divided into two types: refractive and refractive.

The imaging quality of refracting telescopes is relatively higher, but it is high, which is suitable for professional enthusiasts or astronomy enthusiasts; Refracting telescopes are more cost-effective and suitable for beginners.

3.Choose the right aperture and focal length: Home astronomical telescopes generally have an aperture between 50-150mm, and the focal length needs to be selected according to the observation target and purpose.

In general, the larger the aperture, the better the magnification and image quality, but the higher the aperture, and the focal length needs to be selected according to the observation target and use.

4.Choose the right stability: Stability refers to the stability of the telescope base and tripod, if the stability is not enough, it will affect the observation effect, especially when observing at high magnification. It is recommended to choose a product with high stability.

5.Learn about the accessories and functions of telescopes: Some home astronomical telescopes are equipped with star maps and electronic equipment, such as automatic star guidance devices, cameras, etc., which can easily find and track celestial objects, and record observation data, improving observation efficiency and experience.

6.Buying a well-known brand: Choosing a well-known brand of astronomical telescope can ensure product quality and after-sales service, and it is also convenient to repair and replace Nalapi accessories.

7.Read the instructions carefully to understand the correct use methods and precautions to ensure the quality and service life of the telescope.

In conclusion, there are many factors that need to be considered when buying a home astronomical telescope, and it is recommended to do full research and understanding before purchasing, and carefully read the instructions for use after purchase to ensure the quality and longevity of the telescope.

1. Telescopes are worth a penny, and you must not be greedy for cheap land stalls and products from small workshop manufacturers. Some well-known domestic telescope brands have good quality and reputation, there are regular sales points, you can choose your own on the spot, for telescopes below 100 mm, the domestic brand of telescopes is quite cost-effective.

2. According to the individual's economic ability, try to choose a telescope with a large aperture; For beginners to enter Naixiaomen, the general stargazing can choose 7 by 50 binoculars, which is easy to carry. It is recommended to choose 60 mm, 70 mm and 80 mm aperture refractors with better conditions: first of all, it is easy to carry, use and maintain, and can be often brought out for observation; Secondly, even in cities with severe light pollution, it can ** sunspots, the lunar surface and bright celestial bodies such as Jupiter and Saturn.

In addition, it is cheap, and when you buy a bigger and better telescope in the future, you can also upgrade it as a guide scope.

3. There are many brands of astronomical telescopes, and they also have their own advantages and disadvantages. But these are all things that we can afford or that don't affect the introductory learning observations. The most important thing is to choose the right old wither for you.

If you want to buy a telescope at the observatory, you can do so by following these steps:

1.Understand the Observatory's telescope sales policy: Different observatories may have different telescope sales policies, some observatories may sell telescopes directly to the public, while others may only sell telescopes to professional or educational institutions.

2.Visit the Observatory and consult: If the Observatory allows the sale of telescopes to the public, you can visit the Brightness Observatory for a consultation and observe the type and brand of telescopes used by the Observatory.

During the consultation, you can indicate your needs and Bizhen budget to get a more suitable proposal for you.

3.Purchase a telescope: If you have agreed with the Observatory on the type and ** of the telescope, you can purchase it directly from the Observatory. Usually, the observatory will provide you with complete telescope equipment and accessories, such as tripods, lenses, magnifying glasses, etc.

4.Learn how to use it: After purchasing a telescope, you need to read the instructions carefully to understand the correct use method and precautions. You can improve your observation skills by asking the staff of the Observatory or attending a telescope training course organized by the Observatory.

It is important to note that telescopes offered by the Observatory may be of the highest level and may have limited makes, models, and specifications. If you want to choose a different brand, model, or size of telescope, consider buying it from a professional telescope seller or online.

First of all, there are astronomical telescopes in the planetarium that are open to the outside of the leaky zone, but they are not open every day, and they are only open to the public when there are major celestial events. So if the average person wants to use a telescope to see the stars, the best way is to buy one by himself, generally a few hundred yuan to 1-2 thousand yuan telescopes belong to the entry-level level, beginners can buy one and try it. It is recommended not to buy it from the Internet, there is no after-sales service, and the quality is not guaranteed.

It is best to buy directly from a brand manufacturer, with after-sales installation, commissioning, maintenance and other guarantees.

Secondly, it is important to note that the moon and planets (metal, wood, water, fire, earth) can indeed be seen more clearly with a telescope than with the naked eye, and some details that cannot be seen with the naked eye can even be seen, such as the lunar crater, the moons of Jupiter, the rings of Saturn, the circles of Venus, etc. But if you look at the stars with a telescope, they are only a little brighter than they appear to the naked eye, and a little more than the stars you can see with the naked eye. Because stars are so far away from us, they look like just a star, whether with the naked eye or with a telescope.

Finally, I want to say that there are now online simulated telescopes, which are made with software and can simulate the operation of telescopes, but the "images" given are also stored in the database, not the real telescope "looking" with the search type. Even remotely operating a real telescope will only allow you to take a picture of a given target and pass you a **. It's completely different from looking at the starry sky with a real telescope.

It is recommended that Cintron 80EQ is suitable for novices and cost-effective.

Theoretically, as long as the eyepiece is replaceable, an astronomical telescope can be connected to a DSLR camera and a computer. But there are still many that are not good, and there are usually the following situations that should be noted:

1.The camera adapter is usually an optional item and needs to be purchased separately;

2.It is necessary to verify that there is an adapter that matches the camera model (entry-level telescopes may not be compatible with all cameras, and some telescopes with insufficient weights will not provide any adapter rings);

3.Computers usually get images through cameras, real-time observations, other types of sensors are no better than cameras;

4.For entry-level telescopes, you can buy a mobile phone holder directly and you can also shoot the clarity of the moon**;

5.If you want to photograph the starry sky, the first thing you should consider is to buy a high-precision electric and equatorial mount, otherwise, no matter how good the camera is, you will not be able to shoot the nebula.
