How high is the clarity of Jupiter and the Orion Nebula with the Startron 80EP?

The focal length of the 80EQ primary mirror is 900mm, and the maximum effective magnification is about 150x, so you can see Jupiter the size of soybeans and see Jupiter's cloud belts.

It should be noted that looking at planets is different from looking at deep space (nebulae, galaxies, star clusters), the brightness of planets is very high, and it is easy to observe, while deep sky objects are generally very bright, so there are extremely high requirements for the observation environment. To observe deep-sky objects, the magnification of the telescope does not need to be too high, and most Messier objects can be seen at about 30 times, but the aperture should be as large as possible, generally 150mm caliber can be used to observe deep-sky objects well, and 80EQ observation of deep space is not impossible, but the effect is not too good.

In addition, the most important thing is to depend on the environment you are in, and you need to have as high atmospheric transparency as possible and as low light pollution as possible. If the Milky Way can be seen with the naked eye, then it is more suitable for observing deep space. Conversely, if you can only see.

First and second magnitude bright stars, then don't toss, this kind of environment will not have any effect on looking at deep space.

There is another point to remind: looking at deep-sky objects such as nebula galaxies, you basically can't see any color, and more often you can only see a blurry, cotton-like halo, so don't expect to buy a telescope casually to see the colorful nebulae like those on the astronomical **, which is obtained by the single-lens reflex camera for a long time**, and with the naked eye, no matter how good the telescope is, it is impossible to have that effect.

This one is very easy to use, just like it.

Jupiter? It can be seen with the naked eye, but it is very small, two Boguan 80 900 and Xingtran 80EQ are recommended, Boguan is a Chinese famous brand, Xingtran is a world famous brand, look at the nebula, I don't know what you want to see, unpopular or popular?? These two are for entry, and they can be improved in the future, and they can be used for the finderscope, **600 700**Yes, you can see Jupiter, and I also see the rings of Saturn!

Added: Some nebulae can be seen, but the clarity is a headache. Follow-up:

Supplement: You can see the lunar craters, Mars, Venus, you can see the Orion Nebula, the Fairy Nebula, M78, the Crab Nebula, and so on Follow-up question: Is there an astronomical telescope that can see the nebula more clearly?

Answer: Clarity requires a good caliber and a good mother mirror, as well as a nebula membrane, then look at the nebula called a cow! First of all, you need a large caliber, generally look at the Orion Nebula only a cloud of fog, by 1 o'clock in the morning it will be a little colored, this needs a good mirror, who has nothing to get up in the middle of the night to see the nebula, and some nebulae do not shine, if you want to reach the observatory to shoot like that, spend tens of millions!

Buy a 130EQ or a cow anti-class one!

The high-magnification eyepiece is darkened.

The higher the silver rate of the stool, the larger the silver mark, the lower the brightness, the blurrier the image, and the more difficult it is to track.

The focus is adjusted, and the jujube sail banquet is the clearest.

Can you observe Jupiter on the night of July 11? Jupiter is not visible at night in July. You must think of Saturn as Jupiter, right? @第一望远镜商店.

As long as the environment is good, there is less light pollution, Jupiter's stripes are faintly visible, Saturn's rings can be seen, Mars is vaguely visible if it is powerful, and the polar crown is faintly visible, and 80EQ is still very powerful to see the moon! Telephoto refraction is not suitable for looking at nebulae and star clusters, and it is better to see nebulae with a large aperture!

A toy can also expect to see galaxies and nebulae far away.

There are some Messier objects that we can see with the naked eye, such as the M42 Orion Nebula and the Pleiades star cluster.

The limit magnitude of the Centramp 90EQ is 12th magnitude, so you can generally see the stars between the 10th and 11th magnitudes, and there are many Messier objects above the 12th magnitude, and only a few are more than 10 o'clock magnitude, for example: M76 M91 M98 M102 M108 These may be difficult to see, and the rest should be seen if the weather is in the right place.

The subscript is the Messier celestial surface in the order of marathon observations, and you can try to find it in that order.

I'm here to refine the answer.

If the sky is red, and there is no way to see some very bright stars, such as Jupiter, Sirius and some more representative bright stars, then there is no way to use an astronomical telescope to see Messi and celestial bodies, if you can still see these, some dark stars can not see, it is also very difficult to see, so since you have an astronomical telescope, it is better to find a place with less light pollution, so that the astronomical telescope is also more useful.

Hope it helps.

It depends on whether the light pollution is serious or not! It's a few degrees of pollution!

6 mm is enough, 70 caliber should not exceed 140 times. Besides, Jupiter doesn't need a high magnification, 100 times is enough. Not seeing the cloud bands is a matter of contrast.

Cintron EQ70 caliber 800mm, right? A 4mm eyepiece may be possible on a clear night.

"Outside the world of the river, there are Bai mountains.

Du Wuzhong. "Han River Overlook" zhi - Wang Wei. Dao hehe, I didn't answer the wrong question. The version quotes this poem from the right couplet, not a literary appreciation, the problem of the landlord, there is a similarity here.

Imagine the boat floating in the river, looking far away, the mountains that stretch between the heavens and the earth, will there be the beauty on the **, the accuracy on the map?

Set up our little cannon barrels and point to the depths of the starry sky. It is also like floating on the Han River, overlooking the green mountains. Even the majestic mountains are just a thin wave on the horizon. The Orion Nebula in the telescope is nothing more than a small white mist.
