Many people always think that the higher the magnification, the better. Some manufacturers also use false high multiples to attract consumers. In fact, the reasonable magnification of a telescope is related to the aperture of the telescope and the observation method: if the aperture is larger, the magnification can be appropriately higher, and the observation volume fixed with a triangular frame can be higher than the hand-held observation volume. If you buy handheld observation binoculars, 7-20x is enough, and the maximum should not exceed 20x. Otherwise, the higher the magnification, the smaller and darker the observation field will be, and the observation effect will decrease, especially the high magnification. The jitter has also greatly increased, making it impossible to stabilize the observed scenery and making it difficult to observe normally. Genuine Bergoges high-power telescopes have just that perfect balance.
