Whatever you want to ask, please make your question clear through normal grammar.
-
Dividing the objective focal length by the eyepiece focal length is the magnification of the telescope, and you can do the math yourself. You don't give a parameter, how can we compare?
-
The magnification is equal to the focal length of the telescope divided by the aperture of the eyepiece. For example, the eyepiece aperture is 20mm, the telescope focal length is 900, and the magnification is 900 divided by 20 to 45x. However, any telescope has a magnified upper line, beyond which it appears to be a blurry spot of light.
A simple calculation is twice the caliber! If the telescope port is 80mm, the upper line is 160 times! The most important parameter of a telescope is the aperture, and the larger the aperture, the stronger the light conservancy.
The higher the resolution, the brighter the field of view. Of course, the performance of the telescope is also related to the optical structure of the telescope! I suggest you check the information on the telescope.

A general reflecting telescope, just for fun. When toys.
I haven't used it. But this is a short-throw reflection of the spherical surface, and it is estimated that the imaging is average.
-
The 130EQ limit magnification is about 200, and the 4mm eyepiece itself is 162 times, and it is more than 320 times after using the 2x Barlow lens, which is a lot exceeded, and you had better use the mm eyepiece and the 2x Barlow lens is barely enough.
I've seen Jupiter with a 4mm eyepiece and a 2x Barlow scope, and it's very vague indeed.
-
The approximate limit magnification is generally a multiple of the caliber. That is, the limit magnification of 130EQ is 260x. If it is 4mm and 2 times Barrow, it will be over.
However, these are rough algorithms. Specifically, you can try. It doesn't have to be beyond the limit magnification, and you will never be able to see it.
It's just that the amount of light is not enough, and it doesn't look detailed.
-
You should be able to see it, as long as you can find it. Also, to see the nebula, you have to use an eyepiece with a long focal length and a large lens, and what you see is not as gorgeous as the ** on the Internet, and you can generally only see a white fog. Not many details can be seen either.
It is recommended that you find a few astronomical masters or add a few astronomical groups to ask for the real image, and do not expect the average telescope to see the effect of photography**. But the shape of those nebulae is still basically visible. It's just a white mist with a shape.
At 80EQ magnification of 160x, Saturn's rings can be vaguely seen, but at this time, the Saturn you see is only the size of a small mung bean, don't expect any details, after all, it is a consumer-grade telescope. Generally, it is **, you can buy it with confidence. As for the sky of Shenzhen, I really don't dare to compliment it in the urban area, the light pollution is too great, and there are basically no dark stars, let alone nebulae.
It is recommended to buy a telescope and take it to the suburbs to see it, away from light pollution, in order to exert the power of this mirror.

130eq Maximum 260 or so 127 Maximum 250 or so Don't look at ** Whatever the seller writes will believe Those are all deceptive novices Astronomical telescopes with a maximum effective magnification of about 2 times the aperture If the weather is very good, you can add more.
But generally not, the maximum magnification is best not to reach close to it!!
And if you look at Jupiter 361 times, you can clearly distinguish some features like the Great Red Spot, 750 times, which no one has ever tried.
Don't put too much faith that the sellers are fake.
-
I'm using 80eq, magnifying 220x, and Jupiter is about the size of a pin's eye, with a slight markings, and I can see a few Guardians.
-
What is really suitable for masters is probably made by the masters themselves (at least designed by themselves). If you don't even know what kind of telescope you need, can you be called a master? Hehe.
-
A hundred times magnification, only a mirror with a buckle diameter of about 50 is needed. It is recommended that you do not need to buy a fold reversal, just buy a small refraction of 80 caliber. 80EQ is for you. At most, with a 6mm eyepiece, the effective magnification is 160 times.
