There are many types of telescopes, and different telescopes have different performance characteristics. When choosing a telescope, we usually look at its magnification and resolution. Here's a look at a few common types of telescopes and how they behave when it comes to distant objects.
1.Reflecting telescopes
Reflecting telescopes use a concave mirror as an objective to reflect light to an eyepiece located at the other end of the telescope. This design allows the reflecting telescope to have a larger aperture, which allows it to collect more light and improve the clarity of observing distant objects. In addition, reflecting telescopes do not have chromatic aberration problems, making them suitable for observing deep-sky objects.
2.Refracting telescopes
Refracting telescopes use a lens as an objective lens to refract light into the eyepiece. This design makes the refracting telescope have a good imaging effect and is suitable for observing ground targets. However, refracting telescopes may have chromatic aberration issues that affect the viewing effect.
3.Carl Zeiss telescope
The Carl Zeiss telescope is a refracting telescope with a special lens design that effectively reduces the chromatic aberration problem. In addition, the Carl Zeiss telescope has a high resolution and a large aperture, which makes it excellent for observing distant objects. However, the Carl Zeiss telescope has a relatively high **.
4.Cat's eye telescope
The cat's eye telescope is a kind of reflective telescope, which adopts a combination of concave mirror and convex mirror, which makes it have a high magnification and better imaging effect. Cat-eye telescopes are suitable for observing terrestrial targets, but they may be limited when observing deep-sky objects.
5.Subaru telescope
The Subaru telescope is a reflective telescope that uses a multi-faceted mirror design, resulting in a larger aperture and higher resolution. The Subaru telescope does an excellent job of observing distant objects, but it is relatively high.
When choosing a telescope, the choice should be based on the observation objective and budget. Reflecting telescopes are generally suitable for observing deep-sky objects, while refracting telescopes are more suitable for observing terrestrial targets. Among these telescope types, the Carl Zeiss telescope and the Subaru telescope have the best performance when it comes to distant objects. If in doubt, you can consult a relevant professional.
