I don't know what kind of concept the landlord can clearly observe the unearthed star and can see the meteorite of Saturn's rings?? Or can you only see Saturn's rings?? In fact, this concept is extremely vague.
For brands. International famous brands Xingtran Tianwolf These brands are undoubtedly among the best in the world (our country only does OEM).
Domestic famous brands Daguan Boguan Jinghua These brands are relatively well-known in China.
Domestic ordinary brand panda jiehe (jiehe) Haoyue.
The mirror of the domestic introductory play Phoenix virtues.
Other brands don't need to be considered, basically 99,800 times infrared night vision, etc., are generally sold in stalls or wholesale markets **200 yuan or less!
For the aperture of astronomical telescopes and the observation effect.
After reading the landlord's question, I gave the landlord a small calculation.
The floor is mainly made of mirrors of about 60mm diameter.
Light pollution is very high, but the air visibility is high and there are no thick clouds.
It is difficult to see the "Saturn rings" It is difficult to see the "Saturn rings" Venus is smaller than the moon Jupiter can also see the circle and can vaguely see the 4 moons For the Jupiter cloud belt Hehe It's very difficult. Mars is only half the size of looking at the moon without a telescope. The other planets don't have to think about it if they're not masters.
The weather is clear, cloudless, and there is no light pollution or very little light pollution.
At its limit, Saturn can see Saturn's rings (which are also very small) and its moons, Venus, and it can see profit and loss, which is actually about the same as the moon's profit and loss, and Jupiter looks the size of a soybean, and you can vaguely see large cloud bands. And the moons, Mars is still the same, brighter than the one above, and the other planets (Mercury is hard to find, Celestial, Neptune, Pluto and asteroids) all look like dots.
The 90-110 caliber mirror has bad weather, thick clouds and light pollution, and the observation effect is similar to that of 60 caliber, but you can see the details of a larger circular surface.
If the weather is good, the observation effect can be greatly improved.
Mercury can see a circle (must be a master of sufficient astronomical knowledge), Venus can see a dull atmosphere (white object), Venus is larger than the Moon, Mars can see a very red circle and the polar crown of Mars, Jupiter can clearly distinguish cloud bands. And you can see the Great Red Spot and the satellites.
Saturn can be observed that the gap between Saturn's rings and Saturn is black. and satellites. Others Don't want to observe other planets...
For the Moon, a large binocular provides a clear view of the crater.
I want to see other stars, like Sirius, Bighorn, Weaver Girl, etc.
Even Hubble astronomy can't see Pluto's exact form... Because it's so far away ... Other constellations and stars Oh Hubble look at it too...
For the position of Saturn: If you buy it, I will give you the current position of the planet so that the landlord can better make introductory observations.
Finally, I wish the landlord some success in astronomy!

Saturn's angular diameter is about 16 20 times, and 60 100 times magnification is about the same, and Sirius's 80mm aperture telescope can basically meet it, but in recent years, Saturn's rings are facing us sideways, which is difficult to observe.
-
For 80mm caliber is enough.
Basically satisfied.

Summary. Take a look at the moon and the large planets in the solar system, such as Venus, Mars, Jupiter and moons, etc., but because the caliber is still a little small, you can only see a rough idea, and the details on the planets cannot be seen clearly.
The main indicator of an astronomical telescope is the aperture size of the telescope, not the magnification. For amateur astronomers, telescopes with an aperture of more than 200mm can meet the needs.
Can an 875x telescope see Saturn?

First, the so-called 525 times is just a gimmick, the maximum effective magnification of the telescope will not exceed 2 times the number of millimeters of aperture, that is to say, the maximum effective magnification of 76700 is about 150 times, and the magnification that exceeds this is meaningless, and the clarity and brightness will plummet, but the details cannot be seen clearly.
Second, the total magnification of the telescope = objective focal length eyepiece focal length. The focal length of the objective lens of the 76700 is 700mm, and the use of a 4mm eyepiece is beyond its limit, and the extender lens is not needed at all, which is an ornament, the most useless accessory in the low-end telescope box. The most comfortable magnification of the 76700 is to form 70x with an eyepiece of about 10mm, and the astronomical telescope is more important to see clearly than to be able to magnify.
Third, before using the telescope, first calibrate the finderscope, use the low-power eyepiece (the eyepiece with the longest focal length) to aim at the obvious scenery 1000 meters away, such as traffic lights and billboards, and put it into the center of the field of vision, and then adjust the three screws on the finderscope until the center of the scene in the finderscope coincides with the center of the eyepiece, so that as long as the target is seen in the finderscope when looking at the stars, it will also be seen in the eyepiece.
Fourth, telescopes are not all celestial bodies that can see details, and stars are just a dot no matter how magnified they are, only brighter. The planets of the solar system are also visible only Venus, Jupiter, Saturn, and Mars (at opposition). Nebula galaxies can only see a blurry halo in a good environment, and no details and colors can be seen.
5. At present, the apparent diameter of Mars is too small, and at most you can only see a very small circular surface, and you can't see any details other than that. Saturn has missed its best observation period this year, and after the sun sets, Saturn is almost at the horizon. Jupiter will not be visible until the second half of the night, rising due east at about 1 a.m. and near the east of the zenith at 4 a.m., it is so bright that it is easy to identify, and the 76700 can see the round surface, faint cloud bands, and Galilean moons using a 10mm eyepiece.
Sixth, as for the goal of setting a good position during the day and not looking for stars at night, it is impossible to achieve it with your equipment, and if you want to watch the stars in that way, please choose a bench with goto function.

76700, (I don't know if it's jiehe or even whatever) Generally speaking, it is best to look at the surface of the moon, or nearby landscapes and objects such as rooftops, and may get much stronger magnification than the average binocular. If the tripod is not very good, it should be perfectly fine to use it handheld.
The magnification that is generally feasible with such telescopes is preferably below 50x, and it is difficult to provide enough light at higher magnifications for the observer to get a good picture. It is best not to use accessories such as Barlow multiplier lenses and orthodox lenses for this type of telescope, and to use eyepieces with large focal lengths as much as possible to obtain a higher field of view. In addition, the focus of the telescope needs to be carefully adjusted by the focus knob to see the target relatively clearly.
It is recommended to use the roof of the opposite building or the trees in the distance during the day to practice focusing before stargazing.
With a tripod or a stable placement, a magnification of about 35x can probably do some of the tricks of this type of telescope (with a 20mm focal length eyepiece). At this magnification, on a clear night, the telescope should be able to see Jupiter's moons, Saturn's rings protruding prominently at both ends, the disk-shaped white fog of the Andromeda Galaxy, and the blue dense constellation of the Pleiades.
Mars, Venus, Mercury, etc. mentioned by the landlord are very bright targets, as long as they appear in the night sky, even the naked eye can see directly, this telescope should be able to see the disk-shaped shape of these planets under effective magnification, and the dot-shaped shape of the stars is very different. Other goals can also be tried, but may be more difficult in the beginning.
In the initial stage, it will be better if it can be used with a binoculars with an aperture of 50 or more and a magnification of 7 or more to help find a target quickly.

If you see a star, it is likely to be a point after magnification, and usually you say 525x with a multiplier on top of the eyepiece; And the planets you have to look at the star map to see the position of the celestial body you want to see; The weather is also very important, if you have less light pollution and good weather, there will be more natural stars, and some stars will not be visible for various reasons; If none of these issues are the case, see if you haven't focused ...... properly

Hehe. Hello, in fact, there is not much room for choice at such a price point. Among the several telescope brands of regular brands, there are few astronomical telescopes that fit this price range.
60 700 for Boguan, 80 400 for Boguan!As well as 60AZ from the Cintron! These are all relatively early models.
For previous years. These are the ones that may be more suitable for getting started, because ** is cheaper. With the development of it.
Now the entry is already 80 caliber, a refractor with an equatorial mount... If there are conditions, it is still recommended to add one or two hundred and buy one with an equatorial mount. Although it will be more complicated to have an equatorial mount, it will be very convenient, because the earth is rotated, and if you have an equatorial mount, you can fine-tune and track the stars through the equatorial mount, if you don't have an equatorial mount.
That's a very tangled matter. Maybe your daughter isn't old enough to be in full control of herself. But I believe that you, as parents...
It can help her learn slowly. Installing a telescope,For Dad,It's not a problem.,Just look at the manual.。。 In the future, you can let your daughter do it herself to improve her.
's hands-on ability... Nowadays, there are still many parents who buy astronomical telescopes for their children. It may be said that children are now exposed to popular science knowledge relatively early, and now the living conditions can also be supported...
So, I always think it's a good thing. If you have any questions about the need for a telescope, please contact me. Hehe.

The telescope cannot be magnified at will, mainly for several reasons: the resolution limit of the telescope itself, the resolution of 140 The aperture of the telescope (calculated on the basis of observing the most sensitive yellow-green light of the human eye), the magnification of the general telescope should not exceed the number of millimeters of the aperture, at most to the multiple of the millimeter, and the imaging will be very poor if it is more than 2 times; Secondly, once the aperture of the telescope is determined, the passing light is determined, and the larger the magnification, the darker the field of view; Again, due to the atmospheric flow, the magnification will be amplified at the same time as the atmospheric jitter will be amplified, so it is not advisable to use too large a magnification. Guess.
The short-focal length eyepiece that comes standard in the telescope design is determined for the preferences of different observers, and the average observer will not use excessive magnification. The 105mm aperture magnification to 140 times is basically the limit that does not affect the image quality, and no matter how large it is, it is not good. The 80mm caliber is generally enlarged to 100 times is enough, and more than 200 times is only used by a few people who like to use the Pei Shi type.
Beginners are advised to use a refractor, you can refer to my one here.
Friend, after reading the ** you sent, I can tell you that the effect of these pictures is not reached, and it is not enough to see only a small bright spot, but it is almost, you can still vaguely see that there are two small edges and corners next to the stars, which is a graphic halo, but it is impossible to distinguish that it is a ring, such a telescope can only be used for sightseeing, at most you can see the lunar crater, if your main purpose is astronomical observation, such a telescope you will regret when you buy it! Break a leg!
The pole is an equatorial mount.
