What is the approximate price of astronomical telescope?

Mid-range telescopes: Cinda Xiaohei, 80ED, 127 Maca and other telescopes, the price is around 2000 to 4500, and the imaging is excellent, so it can enter celestial photography. The medium-range telescope is suitable for some economic conditions and can be used for celestial photography.

High-end telescopes: Startron C8, 8SE, Cinda SC8, 16 inch DOB, etc. The price is more than 10 thousand more expensive than going to 2W. Planetary weapons, DOB are all in deep space. Generally, a crater with a diameter of more than ten kilometers can be seen with a 50mm refractor of 300~400, and the effective magnification is about 60 times. The limit magnification is 300 times.

Matters needing attention in purchasing astronomical telescope:

1, light collection ability: An important performance of a telescope is its light collection ability. Concentrating light is the ability of a telescope to collect light. The concentrating power is determined by the aperture of astronomical telescope. The bigger the mouth, the stronger the light gathering ability, and the darker the stars you can see.

2. Resolution: Resolution is the shortest distance that can just distinguish two points. The resolution of the telescope is characterized by the limit resolution angle. The smaller the resolution angle, the better the resolution. According to the theory of physical optics, the limit resolution angle of an ideal optical system with an entrance pupil of d is φ= 1.22λ/D, so the larger the entrance pupil diameter of the telescope, the better the resolution. In addition to considering the limit resolution angle of the telescope itself, we should also pay attention to the limitation of the human eye on the limit resolution angle, and the angular magnification of the telescope should be large enough to prevent the human eye from limiting its resolution.
