Questions about the physics astronomical telescope Saturn

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!

I used a 114 900 bull anti + pl6 eyepiece in +3* Barrow to see the satellite very clearly. But it seems to be 450 times.

65 times, at most you can see a bright spot, and if you have better visibility, you can see that there are protrusions at both ends of the bright spot.

I shouldn't see anything, the multiplier is still too small.

However, it is still possible to look at the moon, and the craters on the moon will definitely be seen very clearly.

But if it's appropriate, it's good to buy one.

What would it be like to see Saturn with binoculars with a true magnification of 65x? （ d）

There is another one that is not extravagant.

500 times can reach a

300 times can reach the last one.

As for b, it must be at least 5000 times more.

Should just be a highlight.

An astronomical telescope is a space telescope, which differs from an ordinary telescope as follows.

1. The appearance is different.

There are generally two mirror tubes on astronomical telescopes, the larger one is the primary mirror, which is used to observe the target; The small one is called a star finder, which is used to find a target, and is also called a scope.

A normal telescope is made up of two tubes of equal size.

2. The distance of the observed object is different.

Astronomical telescopes can observe stars other than Earth.

Ordinary telescopes can only observe objects that are slightly closer.

3. Different uses.

Astronomical telescopes are mainly used to observe astronomical changes.

Ordinary telescopes are generally only used to observe objects on the ground.

The precautions for stargazing with astronomical telescopes are as follows:

Before using the telescope, you should first calibrate the finderscope, use the eyepiece with the longest focal length to point at obvious objects such as traffic lights and billboards 1000 meters away and put it in the center of the field of view, 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 scene, so that as long as you see the target in the finderscope when looking at the stars, you will also see it in the eyepiece. When the telescope is stargazing, not all celestial objects can be seen, and the star is just a dot no matter how magnified it is, but it is just brighter. Only Venus, Jupiter, Saturn, and Mars can see the circle of the planets in the solar system.

Liquid nebula galaxies can only see a blurry halo in a good environment, and no details and colors can be seen.

If you use an 80mm aperture refractor you can only see the circle of Venus, the polar crown of Mars (it is difficult to see other details of the surface, if Mars is not at opposition, that is, when it is closest to us), Saturn's rings, Jupiter's cloud belts and the Great Red Spot (faintly visible, if the weather is good), and Jupiter's 4 moons (but you can't tell their apparent circle) and Saturn's rings (Cassini Ring Gap can't be seen clearly) and Uranus and Neptune in the dotted shape but not Pluto ( The big rush is supposed to be only about and so on).

If you use a 150mm refractor or a 200mm mirror, you can see not only the polar crown of Mars, but also some large landforms such as basins and canals on Mars, and even the profit and loss of Mars can be distinguished. Jupiter, on the other hand, is more ornamental, with a great red spot, cloud stripes, and the apparent circle of Ganymede (which should be discernible at high magnifications if you have good eyesight), while Saturn's Cassini Slit and Titan are clearly visible, and Uranus's visual distance can also be seen in your eyes, but Neptune is still a dot, but you can see Pluto (a faint dot-like object).

If you observe these objects with a Meade professional astronomical telescope (400-500mm), you will gain even more. Not only can you see the circles of Venus, but you can also see the cloud bands on the surface after adding color filters, and if you observe Mars, you will see more details on its surface, Phobos and Deimos (these two moons should be visible in the 500mm aperture, depending on the situation), the 13 cloud bands on the surface of Jupiter are clearly visible, as well as the Great Red Spot and the Great White Spot, and even the shape of its elliptical outfit can be clearly distinguished, and the 4 large moons of Jupiter, you can distinguish their apparent circles in the set. The size of the apparent circle of the four moons can be distinguished, and the Callisto Ring can be seen (the shadow of a smaller Callisto obscures two larger Callisto Eurosisto, such as Ganymede, which has a Callisto ring phenomenon) and some of Jupiter's other smaller moons. Saturn's Cassini rings are clearly visible, as are the surface cloud bands, as well as Titan.

Uranus's pale blue surface, Neptune's apparent circle, and Pluto's mysteriously touching side. I have a 305mm Meade Cassegrain telescope at home, and I can see almost all of the above

Well, that's it, if you want to feast your eyes, go to the observatory, which will provide you with the most powerful astronomical telescope (I am the god of wealth in the world).

In my opinion, the Cintron 80EQ is the most cost-effective.
