magnification eyepiece 中文意思是什麼
-
The magnification of any telescope can be changed very easily by changing the eyepiece. even for the largest telescopes, the magnification is seldom over 500, usually between 100 - 200. thus, large telescopes do not magnify more, they only show brighter and sharper images
其實大望遠鏡並不是把天體放得更大，而只是提供一個較光和較清晰的影像罷了倍率是物體視大小的放大比率，例如一個原本視角直徑為1角秒的物體，若放大后的視大小為30角秒，那麼倍率便是30倍。 -
Shorter barlows, or ones with too much magnification, only exacerbate the problem because the ray path entering the eyepiece is steeper
短barlows ，或那些太多的放大，不僅會加劇問題，因為射線路徑進入目鏡是陡峭。
