To observe fainter meteors and make your observations run more efficient, a small telescope with a field of view exceeding 7 degrees or a magnifying power not more than 7 should be employed
為了觀測更暗的流星和提高觀測效率,一個小型望遠鏡可達事半功倍的效果視埸達7度或以上,或放大倍率為7倍或以下。People usually think that larger telescope will magnify the object more. the magnification is the ratio of the apparent sizes of the object. for example, if the angular size of the object is one arc minute and through a telescope, its apparent size becomes 30 arc minutes, then we say the magnification is 30
很多人以為大型望遠鏡可以把天體放得更大,事實上望遠鏡要獲得很高的倍率是很容易的只要改用較短焦距的目鏡便可以了,但就算是大型望遠鏡,倍率也極少超過500倍,一般都只是使用100至200倍。
