What is the difference between a bird-watching spot scope and an astronomical telescope

Although both bird-watching spot scope and astronomical telescopes belong to the category of telescopes, their structures are quite different. How big is the difference between a bird-watching spot scope and an astronomical telescope? Are the functions of the two compatible? These are questions that many people want to understand.

With different appearance and portability, the length of the tube of the bird-watching spotting scope is generally within 40cm, and the length of the tube of the astronomical telescope can generally reach 40c-90cm or even longer. Bird-watching spot scope mostly use refractive optical systems, with a large front end of the lens barrel and a small rear end, while astronomical telescopes have optical principles such as refraction, reflection, and catadioptric, with different shapes.

In conclusion, bird-watching spotting scope are smaller and easier to carry, while most astronomical telescopes are not easy to carry.

The structure of the bird-watching spot scope with different structures is relatively simple, usually there are only three parts: the main tube, the eyepiece and the tripod. You can assemble these directly when you use it.

In addition to the main tube, eyepiece, and tripod, the astronomical telescope has components such as equatorial mount, finder mirror, accessory disk, etc.,. Before use, the finder mirror must be calibrated, which is difficult to install and complicated in structure.

The performance is different. Under normal circumstances, the larger the aperture of the telescope, the stronger the observation ability. The aperture of conventional bird-watching spot scope is mostly between 65mm-100mm. With zoom eyepieces, observation magnifications of about 20-70 times can be achieved. Moreover, due to the compact structure of bird-watching spotting scopes, most of them also have a nitrogen-filled waterproof effect, and the air humidity is relatively high. It can also be used with confidence in the environment.

The caliber of astronomical telescopes is more common from 50mm to 130mm, and some high-end products have a caliber of more than 200mm, and the maximum magnification is often more than 100-200 times.

Applicable to different scenes The bird-watching spot scope is specially designed for bird-watching. It is equipped with a continuous zoom eyepiece. During the observation process, you can gently rotate the eyepiece zoom knob to gradually zoom in on the target, making it easier and more convenient to use. However, due to the limitation of magnification, it can be used to watch larger targets such as the moon, while watching other distant and smaller targets is somewhat powerless. Bird watching scopes is more suitable for bird watching enthusiasts or as an entry-level astronomical telescope and ordinary telescope for children. Astronomical telescopes are specially designed for observing the sky, and even many astronomical telescopes will show inverted images (insensitive to the direction of the object when observing celestial bodies). If you want to change the magnification, you need to replace other eyepieces. The magnification span is large and the observation efficiency is high. You can see More distant celestial bodies. If you use astronomical telescopes to observe ground targets, in addition to the inverted image of some models, the inconvenience of carrying and assembling will also greatly restrict the viewing function.
