Have you ever wondered what it would be like to see the planets of the solar system up close? For amateur astronomers, the answer is simple: you need a quality telescope. With so many options on the market, it can be difficult to decide which one is best for you.

However, if your goal is to observe the planets, the SkyWatcher models are an excellent option. They are known for their ability to provide sharp, detailed images of the planets, making them ideal for astronomy enthusiasts.

In addition, SkyWatcher is a renowned manufacturer in the telescope market and has earned a reputation as a leader in the industry. In this article, we will explain the characteristics and advantages of this brand, as well as discover some points that you should take into consideration when buying a telescope to see planets.

TO CHOOSE A TELESCOPE YOU MUST KNOW THIS

There are two types of telescopes that are most recommended for planetary observation: refracting telescopes and Maksutov-Cassegrain catadioptric telescopes.

Refracting telescopes are the classic telescopes, characterized by their long and narrow tube. They are very resistant, easy to use and do not require maintenance. Also, they are good for observing planets because their lenses (rather than mirrors) provide bright, high-contrast images.

However, the most basic models can exhibit chromatic aberration and poor image contrast. To improve these characteristics, there are two types of higher quality refractors: the achromatic and the apochromatic, which eliminate most or all chromatic aberrations respectively, although they are also more expensive.

On the other hand, Maksutov-Cassegrain telescopes are a type of catadioptric telescope that combines a lens with mirrors. This combination allows for excellent contrast, bright images with a very long focal length in a short tube.

They are slow telescopes and their high focal ratio is ideal for planetary observation. In addition, some models come with automated mounts that allow you to search for the planets more easily, although their price is high.

In summary, if you are looking for a telescope to observe planets, refractors and Maksutov-Cassegrain are the best options. Refractors offer bright images and are easy to use, while Maksutov-Cassegrain have excellent contrast and focal length in a shorter tube.

The choice will depend on your budget and your personal preferences.

 

SKYWATCHER EVOSTAR AZ-3: THE BEST OPTION

This manufacturer is well known among astronomy fans, thanks to its wide variety of options. We can safely say that there is a different SkyWatcher model for every need, with features that will help you get what you are looking for.

Now, going back to the topic that brought us here: which one is the best for seeing planets? We recommend the Skywatcher Evostar AZ-3. But why?

It is an achromatic refractor telescope with a 90mm aperture, which will allow you to see more celestial objects and have brighter images. In addition, it has a long focal length of 900mm and a high focal ratio of f/10, which will help you to have sharper images with less chromatic aberrations when observing planets.

What does that mean ? That you can use different eyepieces to have more magnifications and see the planets from closer.

The included AZ3 altazimuth mount is easy to mount and operate, and is more robust than other common mounts, allowing you to aim more accurately and reduce vibrations. It also comes with two eyepieces, a 2x Barlow lens, a 6×30 telescope finder, and an inverting prism video porno.

By using it you will be able to appreciate the details of the planets more clearly, and you will be able to distinguish even the shadows generated by the craters of the Moon. The high focal ratio will also help you observe celestial objects that are not very large, making it ideal for planetary observing.

MOST POPULAR CONSPIRATIVE THEORIES

Posted on by Edmitchellapollo14

MOST POPULAR CONSPIRATIVE THEORIES

The existence of aliens on earth, reptilian beings, secret societies and the dark plans of Tik tok in the West… yes, the internet is full of conspiracy theories, each one more crazy than the last.

However, among all the laughable and somewhat impossible approaches, there is a small part of them that have become popular among the internet community, either because of their high probability of being real or because of the insane nature of their approach.

In any case, as getting bored is not an option and it is always good to have all kinds of conversation topics, today we have compiled for you a list of the most popular ones.

3 CONSPIRATIVE THEORIES THAT WILL LEAVE YOU THINKING

3 CONSPIRATIVE THEORIES THAT WILL LEAVE YOU THINKING

IS THE EARTH… FLAT?

We start the list with this theory, more than conspiracy, conspiracy. It is known as “flat earthism”, a school of thought that affirms that the earth is, without a doubt, flat instead of round. This theory found its origin between the 19th and 20th centuries, among a group of people who did not believe in the theoretical assumptions of Erastothenes and Aristotle, who laid the foundations to discover that the earth is round.

Those who currently believe in these conspiracy theories also resent the current evidence that man ever landed on the Moon. Likewise, they affirm that the space photographs that we currently have are false porno français.

THE STORY OF THE FIRST MAN ON THE MOON IS FALSE

Remember that group of people who believe that the earth is flat? Well, for the most part, they are the ones who encourage this theory. After almost half a century of antiquity and countless proofs, there are still those who believe that the first man on the moon was a fictional set-up by NASA, with the help of Hollywood.

To support the theory, they are based on images broadcast on television, where you can see the waving United States flag stuck to the lunar surface. But… how could a flag fly in a place where there are no drafts? In addition, it is not unreasonable to think that, at the time, it was “too convenient” for these images to be transmitted.

Does that mean that this theory is true? Well no. Experts in the area affirm that the flag was never waving in the video. In fact, the astronauts had to deploy it with their own arms. What critics call “wave” is nothing more than the flag itself completely wrinkled.

 

THERE IS A HOLE IN THE CENTER OF THE EARTH

Do you remember that movie “Journey to the Center of the Earth”? Those who believe in this latest conspiracy theory took this movie too seriously. Although they affirm that, indeed, the earth is spherical; they establish the premise that, at the center of the wait, there is some kind of star or source of energy.

Certainly there are studies that affirm with solid foundations that the earth is completely solid inside. However, those who believe in this conspiracy theory do not rule out the possibility that there are even living beings living there.

Now that you know the most popular conspirative theories on the internet, do you think you could believe any of them?

THE WEBB TELESCOPE REDISCOVERS THE UNIVERSE

Posted on by Edmitchellapollo14

THE WEBB TELESCOPE REDISCOVERS THE UNIVERSE

Since its commissioning, the incredible James Webb Telescope has allowed us to see the universe as never before. On 5 September 2022 it offered its first images to the world, demonstrating the immense capability of its infrared-sensitive technology.

Thanks to its unique configuration and location, just under 2 million kilometres away at the L2 Sun-Earth Lagrange point, it can capture images of the observable disc of Mars, spaces never before seen in such high quality detail.

Its photographs and spectra now allow scientists to study very short-term phenomena that previously seemed unattainable, such as dust storms, weather patterns and even seasonal changes.

 

THE KEY CHALLENGES

There is no doubting the immense capability that James Webb brings to modern science. However, it was not easy to arrive at this result.

To understand the issue, let’s reflect a little on our interstellar neighbours: the moon, the stars and, of course, Mars. There is no doubt that the Red Planet xxx is one of the brightest objects in our space firmament. After all, it is easy to see it even at night with no other tool than your eyes.

This presents an incredible challenge for researchers using the James Webb Telescope, as the light emanating from this celestial body is extremely high, while the original James Webb configuration is intended to capture extremely faint light from much more distant galaxies.

To circumvent the sensitivity of the James Webb and avoid “detector saturation”, special techniques had to be developed and applied in the observing process. One of the measures was, for example, to take only a part of the brightness of Mars for very short exposures. In this way, it is possible to perform the analysis.

 

THE LONE STAR

Several pictures from the James Webb Telescope have already been trending on social media. Stars, galaxies and celestial bodies are available to our eyes for the first time in incredible resolution.

However, one of the most surprising discoveries for scientists comes not from a gigantic planet or a distant galaxy but, instead, from a single, solitary star shining hundreds of light years away: Earendel.

Or shone, more precisely. After all, the fact that we can see its light right now means that millions of years ago that light was probably already extinguished.

THE LONE STAR

According to the scientists’ analysis, it is very likely that we are looking at the few remaining remnants of Population III, the first stars that emerged in the Universe after the Big Bang.

According to current knowledge of these ancient celestial bodies, they are thought to have consisted only of primordial hydrogen and helium. The reason? No other component or material existed in nature or space.
Therefore, the brightness of this lone star gives us insight into the origin of the heavier atoms that would later form as the result of nuclear reactions triggered by other celestial bodies exploding.

According to the information available so far, it is estimated that Earendel, which we see today as a small, solitary star, had a mass 100 times larger than the sun, as well as a temperature of 20 000 degrees Celsius. This is the reason for its brightness, with a slight bluish hue.

Even so, as it is not a supernova, we should not be able to see it from our position. Therefore, we have a strange and fortuitous coincidence to thank for its recording.
