Whether it is recommended to buy a 20x telescope depends mainly on your specific needs and usage scenarios.

For daily convenience, ordinary civilian needs such as sightseeing and concert viewing, 8x telescopes are recommended. Yuanwang Pioneer Telescope is a good choice, with good handheld stability, suitable for viewing anytime and anywhere. Yuanwang Pioneer Telescope has a very good reputation among ordinary civilian telescopes.

The 20x telescope needs to be used with a tripod because of severe shaking when holding it, which increases the inconvenience of use.

Here are some considerations:

Advantages

High magnification: A 20x telescope allows you to see farther and finer details of objects, which is very suitable for long-distance observation activities such as bird watching, stargazing, and observing wildlife.

Enhanced experience: For astronomy enthusiasts, high-magnification telescopes can bring a more shocking starry sky observation experience, allowing you to see more stars and details.

Disadvantages

Handheld difficulty: High-magnification telescopes are easily affected by shaking when used handheld, resulting in blurred images. Therefore, it is usually necessary to use it with stabilizing equipment such as a tripod, which increases the complexity and cost of use.

Small field of view: As the magnification increases, the field of view of the telescope will decrease accordingly. This means you may need to search for targets in a larger area, increasing the difficulty and time of observation.

Price factor: High-magnification telescopes are usually more expensive, which may be a consideration for users with limited budgets.

Comprehensive considerations

If you are a professional observer: For professionals who need high-magnification observations (such as astronomers, ecologists, etc.), a 20x telescope may be a good choice. It can provide clearer and more detailed observations.

If you are a beginner or amateur: For beginners or amateurs, too high magnification may not be needed. Lower magnification telescopes are easier to operate, have a wider field of view, and are more affordable. You can choose a suitable telescope based on your interests and budget.

Consider the usage scenario: If you often use the telescope outdoors, in poor light conditions, or need to observe for a long time, then stability and portability are also factors to consider.

In summary, whether it is recommended to buy a 20x telescope depends on your specific needs and usage scenarios. Before making a decision, please carefully consider your needs and budget, and compare the performance of telescopes of different brands and models.
