If you look at the nebula, choose a slightly larger magnification (I mean you can choose an eyepiece with a shorter focal length, such as 9mm 6mm, etc.).
Theoretically, this is not a matter of price, the greater the magnification of the telescope, the farther you can see, and the larger the aperture (the diameter of the head and neck at the end of the light), the larger the amount of light, the clearer you can see.
Astronomical telescopes are not measured in multiples. The larger the objective aperture, the better (depending on your budget).

Depends on how much you're going to see.
The Large Magellanic Nebula is visible to the naked eye (sufficely, I haven't seen it anyway).
If you want to see the M series, it's better to buy a better one. In fact, it's good to have a few hundred to play, and after you get familiar with it, buy a 1000-thousands of slightly high-end goods, and slowly cultivate it.

The caliber should be 120, at least the second-hand should be 1000, 2000.

Beijing Galaxy Telescope Answer:
The gap between astronomical telescopes is very large, and our ordinary junior astronomy enthusiasts can choose non-professional mirrors
Professional mirrors are very expensive and are generally used for professional observations). **At.
Of course, if you are very passionate about astronomy and have high requirements for observation effects, you must choose a mid-to-high-end telescope, refraction and reflection have their own advantages and disadvantages, mainly depending on what you want to observe, choose the best one that suits you.
The refractive aperture is relatively small, the focal length is relatively long, and the realization multiple is relatively high, which is more suitable for seeing the single planet and details, but it is easy to maintain, simple to operate, and the low-end refractor is relatively cheap, which is more suitable for beginners.
The reflective type has a large aperture, a short focal length, and a relatively low realization multiple, which is more suitable for seeing a large area of the starry sky and a large observation field, but it needs to be coated once every five years.
The realization multiples mentioned above are relatively speaking, the magnification of astronomical telescopes is directly related to the eyepieces, and the eyepieces that are standard with each model are different and cannot be generalized. For beginner astronomy enthusiasts, it is still recommended to choose the refractive type.
For the entry-level astronomical telescope, the Startron.
90EQ (refractive) and.
130EQ (reflective) is a good choice.
90EQ This can see the crater on the surface of the moon, can see Saturn, Jupiter, Jupiter moons, etc., can also view the scenery, can see the trademark of one or two kilometers of air conditioning, this basic configuration is very good, the imaging effect is also great, **in.
Yuan or so. 130eq
You can see the craters on the surface of the Moon, Saturn's rings, Jupiter, Jupiter's cloud belts, Jupiter's moons, etc., at the same time.
The 130EQ is basically a civilian astronomical telescope that can take pictures of nebulae with the lowest aperture requirements after being connected to a camera. **At.
Yuan or so. 130eq
The relative aperture is large, and the observation field is large.
You can go to the Galaxy Telescope Knowledge Zone to take a look and search directly.
Galaxy Telescope.
Yes, there is a lot of knowledge about the purchase, maintenance and use of telescopes
Amateur astronomers generally control the multiples of mirrors within 200 times, and less than 100 times to see the moon. The landlord said that 500 times is too general, can you be specific. Almost 70 times you can see Jupiter's extreme moons, Saturn's rings.
The pole is an equatorial mount.

**Proportional to the square of the aperture (i.e., the area of the primary mirror). If you have money, you can see details such as the spiral arm of the extragalactic galaxy with an aperture of more than 200mm, and a spot of light below 200mm. The same is true for nebulae, the stars are one point anyway, even with Hubble, but large aperture can distinguish more binary stars, polyconjunctions. >>>More
The most important parameter of a telescope is the aperture, which determines the telescope's ability to gather light, as well as important parameters such as resolution. >>>More
It's hard to say! I saw it at the store of Sheshan Observatory in Shanghai, which cost more than a dozen yuan. Although I haven't seen it, I guess I can see it if I look at the Moon Crater. >>>More
