Which of these three astronomical telescopes is better?

1 is Boguan Trailblazer 70 900, in fact, the difference between the three is really not big, it really has to talk about the main ones:

1 joule ratio. First of all, their caliber is about the same, 80 is about twice as good as 70 light, and the limit magnitude is about high, which has no effect on beginners, and it can't be seen in actual observations. The focal ratio directly affects the target and magnification of the celestial object you are looking at, the smaller you look at the nebula cluster, the more advantageous these deep-sky objects are, the larger the area, and the corresponding magnification is relatively smaller; The opposite is true for large focal ratios, which are better for galaxies and binary stars.

70 900 is, 70eq is 10, 80eq is. I think it's better for beginners to have a smaller focus than a smaller one, because you tend to be more interested in deep-sky objects. The field of large focal ratio is the world of reversal, and the small focal ratio is the reverse of the bull.

Let's be honest and look at your own goals.

2。Brand. Centron is an American, telescope giant, much better than Boguan, which is only famous in China; Of course, some of its products are manufactured by other factories, and the quality will decline. Overall, both of these are okay for beginners.

3**。Both the Trailblazer and the 70EQ are 900, and the 80EQ costs 1300, depending on your budget, but in short, I think the price is acceptable (considering the brand and configuration).

4. Portable. The telescope is to be taken to see, and it must be moved out often, otherwise it will become an ornament. You can't squat on your balcony or build a simple observatory in an open space every day (in general), so it's important to consider portability.

The other items are similar, eyepieces, finderscopes, tripods, manual equatorial mounts, all are standard, the interface is also standard, and the remaining data such as magnification has been determined above, no problem. There is one point: the Barrow mirror used by Xingtron is 3 times, and the CD is sent, which is not the key, depending on the landlord's preference.

In summary, if you have a budget and it is best to carry it easily (such as having a car), buy 80EQ; The budget is small but the focus on focus ratio and portability, 70EQ; The budget is small but the multiplier is very important, 70 900.

I personally prefer the 70EQ. Let's take a trade-off, don't worry too much, it will be upgraded in the future, hehe.

Boguan 70 900 has more than 110,000 followers on the official website "Tianzhiwen", creating the most forum of the forum. Founded in 2002 in the Shanghai Astronomical Observatory, the Shanghai Boguan Telescope Store has sold the best in 10 years, and another reason why this telescope has sold best is that the observatory teacher gives beginners guidance on how to use this telescope for astronomical observations. Even if you're just in junior high school, or you're in elementary school.

In the fourth and fifth grades, they can also operate and use independently, and some can also photograph the moon. If you buy it, you won't use it, and you will soon lose interest.

This telescope can also be equipped with a special soft backpack, which is easy to carry when you go out.

The performance of the three telescopes is about the same, and they can be used for beginners, but in view of the fact that beginners do not understand in many places, it is better to buy a domestic Boguan, at least the after-sales is still guaranteed.

No. 3 recommended. At present, the 80 caliber is more popular, that is, it is slightly more expensive, 70 is chicken ribs, and the Boguan is too heavy.

However, these are based on your full understanding of the knowledge of the starry sky and the assistance of binoculars, for beginners, you must have binoculars to know the starry sky, otherwise it is a waste to buy a single tube.

In my recommendation, not necessarily the best. But I think the Cintron 70EQ

It's better.

Boguan 70 900 astronomical telescope.

I'm also a beginner, I want to buy this, but I don't know where to buy it, my family comes to Shenyang, nearby, I don't know if I bought it, Taobao has it, but I don't know if it's credible.
