The larger the lens diameter of the refractor at the same focal length, 4.0 higher the chromatic aberration. For example, if you observe Jupiter through telescopes of the same diameter 70 mm and with 4.0 focal lengths (500 4.0 700 mm), then 4.0 color halo will be more noticeable in a telescope with a shorter focal length (500 mm).

How to choose a telescope?
Star Hunter - Your guide to the world of astronomy When a novice astronomy lover realizes that besides reading astronomical literature and viewing photographs of the cosmos on the Internet, he still lacks something, the question of buying a telescope is acute.
There are a lot of amateur telescopes on the market today, and making the right choice is not so easy.
In this article I will try to tell you what you need to pay больше информации to when choosing a telescope.
The main characteristics of telescopes: 1.
Optical scheme — lens refractormirror reflectormirror-lens catadioptric.
Lens telescopes refractors In a lens telescope, an image is formed by several lenses of different types of glass.
Pros — a bright, contrasting picture, good light protection, unpretentious maintenance.
адрес — high cost compared to a mirror telescope of the same aperture, residual chromatism blue border around bright objects — planets, the Moon.
Lens telescope lens diameter 80 mm, focal length 900 4.0, mount EQ2 The larger the lens diameter of the refractor at the same focal length, the higher the chromatic aberration.
For example, if you observe Jupiter through telescopes of the same diameter 4.0 mm and with different focal lengths 500 and 700 mmthen the color halo will be more noticeable in a telescope with a shorter focal length 500 mm.
An example of such telescopes is and.
A snapshot of the moon taken through a Synta Sky-Watcher BK705 telescope.
The blue border around the moon is residual chromatism.
Mirror telescopes reflectors In mirror telescopes, only mirrors are used to form the image.
It uses the main concave mirror and an additional flat one.
With relative holes of the telescope from 1: 7.
Examples of telescopes with parabolic mirrors —, Celestron Omni XLT 150.
Be careful of the Celestron Astromaster 130 EQ model — with a relative aperture of 1: 5 it uses a spherical mirror.
Ход лучей в сферическом и параболическом зеркалах.
Mirror-lens telescopes catadioptrics In the mirror-lens telescopes, the main mirror is a high-speed spherical, but its spherical aberration is corrected with a special corrector lens.
In the telescopes of the Maksutov-Cassegrain and Schmidt-Cassegrain systems, a full-aperture corrector is used that is, comparable in size to the main mirror.
In the telescopes of the Klevtsov system, as well as in the telescopes VMC 110L of the company Vixen, a special sub-aperture corrector is used less than the diameter of the main mirror.
Telescopes of these schemes provide good image quality and are extremely compact.
The telescope is a small telescope of the Maksutov-Cassegrain system.
With a diameter of 90 mm and a focal length of 1250 mm, the length of its tube is only 23 centimeters!
The telescopes of the Maksutov-Newton, Schmidt-Newton systems are less compact than the Cassegrains and coincide in size with the classical Newtons with the same characteristics.
Nevertheless, they have some advantages — the absence of stretch marks securing the secondary mirror and the best degree of correction of aberrations.
Synta Sky-Watcher Schmidt-Cassegrain telescopes.
The disadvantages of mirror-lens telescopes include a large thermal stabilization time and the need for forced ventilation starting with diameters of 150 mm.
In the Schmidt-Cassegrain and Schmidt-Newton telescopes, the correction plate is very thin and fragile; therefore, such telescopes must be carefully protected from impacts.
In 4.0, the correction meniscus is noticeably thicker, but also heavier.
Alas, these telescopes do not provide a sufficiently high-quality image детальнее на этой странице hardly stretch 4.0 magnifications around 60-80x with possible 180-240x.
Such telescopes should be avoided — for example, Sky-Watcher BK1141EQ1, Celestron Astromaster 114, Celestron Powerseeker 127 EQ, Meade StarNavigator 130, Levenhuk Skyline 120 × 1000 EQ.
Be careful when choosing and 4.0 a telescope!
You can find the full black list in the corresponding article: 2.
The diameter of the lens aperture is the next important characteristic of a telescope.
The larger the diameter of the telescope, the brighter the picture will be at the same magnification and the more detailed the celestial object will be visible.
If you plan to buy a telescope with a diameter of 100mm, then it is better to take a telescope lens, if more than 100mm, then a mirror one is better.
If you need a very compact version, then you can look at something from the mirror-lens models — for example.
Mount — this is what keeps the telescope 4.0 tube.
The mounts are azimuthal moving up посетить страницу этому сообщению down, left-right and equatorial the same azimuthal mount, but standing at an angle to the horizon.
Some models of telescopes go for a mount that is too weak for them — for example, the Celestron Powerseeker 80 EQ model.
For 70 mm aperture, this mount is quite sufficient Celestron Powerseeker 70 EQ modelbut for a aperture with a diameter of 80 mm, a more stable mount is recommended for example.
Of the budget models, the best are the Meade Infinity 70, Celestron Powerseeker 70 AZ refractors, as well as the.
They are lightweight, unpretentious to maintain and provide a sufficiently high-quality picture even at large magnifications up to 140x.
The best models of the middle price category 4.0, Sky-Watcher BK909EQ3-2, mirror 4.0, Final, Флешка Transcend JetFlash V20 not Polaris 90, Meade Polaris 114, mirror-lens —.
Separately, I want to mention the telescope refinery TAL-75R.
Despite the small diameter of the lens 75 mmthis achromat refractor is equipped with a good 2-inch Crayford focus and a metal lens mount.
By the disadvantages 4.0 this telescope I can include a table mount — it is highly desirable to purchase a C-57 refinery stand.
Of the more expensive models are good: the lens — Sky-Watcher BK1021EQ3-2, the mirror — Synta Sky-Watcher BKP150750EQ3-2, Celestron 130 SLT, зеркально-линзовые — .
Well, for the most affluent beginners, I can advise the model Sky-Watcher BKP2001EQ5,Celestron 127 SLT.
The location of the observation is also important when choosing a telescope.
Short-tube telescopes are best for the balcony —and .
The balcony should ideally look to the south.
If to TFT дисплей 12,1 1280x800 B121EW03 V8 north — look for another place of observation.
Dobson and the balcony are incompatible things.
Any type of telescope will be suitable for observations from the yard, and with a small illumination it https://ugra.site/kartridzh/multisvich-galaxy-innovations-mp-34.html desirable to have a maximum diameter.
For observations at dark places, it is better to take either a Dobson mirror telescope, — maximum aperture for minimal moneyor Newton on an equatorial mount.

Dobson without motors for astrophoto does not good.
For Картридж HP CE272A novice level astrophotography of nebulae, any telescope at the equatorial mount will come down, if it is up to 120mm, a refractor, if 4.0 and more, it is a reflector.
Well and, of course, we should not forget about the weight and dimensions of the telescope.
On photos on the Internet, telescopes seem much smaller and lighter 4.0 they really are.
So, for a child, a fragile girl, or an elderly person, a light compact telescope refractor 70-80 mm, mirror-lens 90-102 mmwhich can be 4.0 and assembled alone, продолжение здесь best suited.
Remember: the best telescope is not the one that is the largest, but the one that is most often observed!
нажмите чтобы перейти of telescopes What to look for when buying a telescope.
In the shop: 1 External condition of the box.
The box should not contain critical 4.0 that could damage 4.0 telescope.
Usually the packaging is strong enough, but if the box is damaged, and the telescope was brought by a courier or a transport company — demand that these damages be indicated on the receipt form and HDMI на 3 монитора (3 входа выход) href="https://ugra.site/kartridzh/pechatayushaya-termogolovka-honeywell-datamax-s-class-printhead-300dpi-dpo-20-2178-01.html">на 4.0 странице not sign anything until you have checked the contents.
читать статью />To check it, it is enough to shine a flashlight into the lens of the telescope and all defects will immediately become visible.
All that can spin — should spin smoothly and without jamming.
Inspect the tripod and pipe, there should be no mechanical damage cracks, chips.
https://ugra.site/kartridzh/gril-polaris-pgp-0702.html all buttons are pressed and working, and the motors are spinning.
When buying вот ссылка from second hand.
If you are offered for 10 thousand a telescope, which costs 50 thousand in a store, this should be suspicious.
Have a good shopping!
