Ask about an entry level telescope and be taught how to choose a telescope!

Hehe, landlord, don't be fooled, I opened this web page and looked at this telescope at a glance and knew that it was fooling customers.

525 times?! No way! Many producers use this parameter to fool people.

Does a 60 caliber mirror know what the limit magnification is? Generally 120 times! The quality can be higher, but for this mirror, it is already a miracle to reach 120 times.

So after buying it, the landlord may regret it and not use it at all. Because the effect of this mirror is really limited, the quality is not good, and 380 fast money is very expensive for this mirror!

Let me compare it with you, more beginners choose the Xingtron 80EQ, about 600, but what can you get? First of all, the diameter is 20mm larger, and the diameter is like life for the mirror, and the light collection power of 80 is more impressive than that of 60. Furthermore, the 80eq is the equatorial mount, which is much better than the theoll and weft of the small mirror.

The help for a beginner is also quite huge! And the quality is absolutely ***.

So it's really not a wise move to choose your mirror!

If you really want to enter the telescope (stargazing), the brand is also a very important, some counterfeit mirrors have appeared greatly in recent years, seriously damaging the interests of enthusiasts, so don't be greedy for cheap and buy a "furnishing" ...... that can't be used at allAt present, the domestic products with good reputation and quality are Xingtlang, Boguan, Daguan, Tianluo, etc., followed by Zhitong, Panda, etc.

If the landlord is tight on hand, it is recommended to save it and buy an 80eq in the future, which is better than buying a "furnishing" back.

This is my heartfelt advice to you as an astronomy enthusiast.

Hope it helps you a little bit, o(o

It is enough for beginners to use this set of telescopes, there are different requirements to choose different telescopes. Telescopes have refraction and reflection. This is a refracting telescope.

Refracting telescope advantages.

Easy to use and simple to manufacture. Ideal for observing moons, planets, binary stars, and especially for telescopes with large apertures. Compact and requires no additional maintenance.

The closed barrel attenuates the damage to image quality caused by air flow while protecting the optical lens. Easy to carry and suitable for long-distance outdoor observation. Secondary imaging can be avoided and a high-contrast image quality can be formed.

Through the achromatic design, the appearance of color aberration can be well avoided.

Cons**More expensive than Newtonian or Cassegreen type. At the same aperture, refracting telescopes are heavier, longer, and larger than Newtonian or Cassegreen telescopes. Due to the limitation of aperture, it is not suitable for observing deep-sky objects such as extragalactic galaxies, nebulae, etc.

The disadvantage of the small focal point makes it difficult to photograph deep-sky objects with refracting telescopes. In the achromatic design, the color of the resulting image will be more or less distorted.

Advantages of reflecting telescopes Because the cost of mirrors is much lower than that of lenses, for large-aperture telescopes, they are often made as reflective instead of bulky refractory. The portable design of the reflecting telescope, although the tube is only 500mm, the focal length can reach 1000mm. Newtonian mirrors have focal ratios of f 4 to f 8, making them ideal for observing faint extragalactic galaxies and nebulae.

Sometimes it is also good to use such telescopes to observe the moon and planets. If you want to take pictures, it's very good when using a Newtonian telescope. But it's a little more cumbersome to use than a retroreflective telescope.

The Newtonian structure concentrates light very well and gives a very bright image at the focal point.

Disadvantages: The open tube type air can circulate, which will not only affect the stability of the imaging, but also some dust will enter the lens barrel with the flowing air and adhere to the objective lens, which will destroy the coating on the surface of the objective lens in the long run, and reduce its reflective power. Since objective lenses with this structure are prone to breakage, you need to be careful when using them. For off-axis light, Newtonian telescopes produce coma.

Telescopes of this structure are not suitable for observation of terrestrial landscapes. Newtonian telescopes are usually larger in aperture and size, so they are more expensive. Due to the addition of a secondary planar mirror, some light is lost.

It can be disassembled and selected by referring to the specifications and coatings of the telescope.

First of all, the specifications of the telescope are the basic of the basics. The best binoculars on the market are marked with a number like "7x35", the front number represents the magnification, and the back is the diameter of the objective aperture. If you are using a telescope to see the scenery, performances, and competitions, it is generally best to use a magnification of 7 or 8 times.

If you look closely, you will find that the mirror surface of the telescope has many colors, red, blue, green, yellow, purple, etc., which is the coating. The coating can improve the light transmittance, increase the contrast and sharpness of brightness and color, and improve the observation effect. Generally, the more coating layers, the smaller the reflection, the better the effect.

Telescope maintenance method

1. Ensure that the telescope is stored in a ventilated, dry and clean place to prevent mildew.

2. The remaining dirty spots or stains on the lens should be gently wiped with a professional lens cloth to avoid scratching the mirror, if you need to clean the mirror, you should use absorbent cotton dipped in a little alcohol, wipe from the center of the mirror along a direction to the edge of the mirror, and constantly replace the absorbent cotton ball until it is wiped clean.

3. The telescope is a precision instrument, and it is important not to make other drastic movements on the telescope.

4. Non-professionals should not try to disassemble the telescope by themselves and clean the inside of the telescope.

The specific selection method is as follows:

1. Sturdiness.

Telescopes are mostly used outdoors The plastic shell is not very protective, and it is easy to shift the prism group due to excessive temperature changes.

2. Weight and feel.

The telescope should not be too heavy, otherwise it will make people tired after a long time of use, make the hands tremble and unable to see the target clearly, and the telescope should not be too light, otherwise it is easy to operate and watch stably due to shaking. With the ergonomic combination of Swarovski, the products enjoy a good sense of balance and a first-class feel, making the most of their optical properties.

3. Magnification (should be between 8 times and 10 times).

The telescopes are marked with the words 10x42'8x30, the former representing magnification and the latter representing the objective diameter. Using a 10x telescope to see a bird standing at 100 meters is as close as seeing it with the naked eye at 10 meters.

4. Generally, the handheld should not be more than ten times, because the multiplier is too high and easy to shake too much, and it is impossible to see the target clearly, especially the military, there are almost no more than ten times at home and abroad, so don't think that the military is shouting that the fight multiple is high, and it is best to use 7-8 times at ordinary times, because high multiples generally mean that the field of view is relatively narrow, and the field of view is very narrow.

5. If you just look at the scenery and travel, 8*40 is already the limit, and 7*50 is too heavy, so it is not recommended to choose.
