Astronomical telescopes are used to observe the seven planets. How to buy them? Can it be used to observe the sun?

Usually, refraction telescope or seglin telescope will be used to observe the seven planets. Because compared with other kinds of telescopes, these two kinds of telescopes are easier to get higher magnification, and the magnification of planetary observation is the key.

There are two types of refraction: achromatic and APO. The common achromatic formula is relatively cheap, representing AstraZeneca's 80EQ and 90EQ, and the price is below 2000 yen. APO is an excellent equipment, with excellent imaging and naturally more expensive. On behalf of 80 granny, Yuzhong 130 granny, Gao Qiao APO. The same 80mm caliber, the common achromatic color is about 800, while APO is 4000-5000 turns.

There are two types of Ka-seglin style, namely "Schmidt-Ka-seglin" for short Zeca, and "Maksutov-Ka-seglin" for short Marca. These two kinds are a bit complicated, but the imaging effect is not bad, slightly worse than APO.

In short, if the budget is below 65,438+0,000 yuan, buy the general expenses; 1000-2,000 yuan 100mm maka (such as a certain model); 2,000-4,000 yuan for/KOOC-0/50 mm caliber MACA (for example, a crown set of three/KOOC-0/50 mm MACA); 4000- 10000 yuan to buy 80- 100mm APO or a C8 Zeca. 10000-20000 You can buy 100- 120mm APO or a Zeca with C925. It is not recommended to rise.

In any case, with so much money, you have to be familiar with every kind of equipment before you can really choose the one that suits you. It is recommended to visit the forums and exchange ideas.

There is also the problem of watching the sun. All telescopes can see the sun, but they should be equipped with "Budd film" or "Herschel prism". Observing the sun directly with a telescope will lead to blindness, so be careful! !
