无论是野外考察、旅游观光,还是文艺演出、体育比赛,望远镜都是最合适的观测工具。怎样选购一架合适的望远镜呢?规格表示:如7×35表示该镜为7倍,口径35毫米。关于倍数:很多人总认为倍数越高越好,一些厂家也以虚假的高倍来吸引消费者。实际上,一架望远镜的合理倍数是与望远镜的口径和观测方式相关的:口径大的,倍数可以适当高些;用三角架固定观测的可以比手持观测的高些。一般单筒望远镜口径和倍数都较大,但其灵活性、舒适性较差,寻找目标也不方便。我们最常用的还是双筒型手持望远镜,一般7～10倍之间足够用,最高不要超过12倍,否则倍数越高,观测视场就越小、越暗,观测效果反而下降,尤其是高倍带来的抖动也大大增加,使观测的景物无法稳定下来。世界各国如美国、俄罗斯装备部队的望远镜大多以6～10倍为主,这是因为一个清晰而稳定的 Whether it is field trips, tourism, or theatrical performances, sports competitions, binoculars are the most appropriate observation tools. How to choose a suitable telescope it? Specifications that: such as 7 × 35 that the mirror is 7 times the diameter of 35 mm. On the multiple: Many people always think that the higher the better times, some manufacturers also to false high times to attract consumers. In fact, the reasonable multiple of a telescope is related to the telescope’s caliber and observation: large caliber, multiples can be appropriate higher; fixed observation with a tripod can be higher than the handheld observation. General telescope diameter and multiple are larger, but its flexibility, comfort is poor, looking for the target is not convenient. Our most commonly used binoculars handheld telescopes, usually enough between 7 to 10 times, the maximum not more than 12 times, otherwise the higher the multiple, the observation field of view is smaller, darker, but the observation effect decreased, especially the high The jitter also increased greatly, making the observed scenery unable to stabilize. Most countries in the world such as the United States and Russia have 6 to 10 times as many telescopes as their armed forces because of a clear and steady
