视

The true field of view depends on the linear scale of that field stop, as determined by the magnification of the eyepiece in that telescope.

有效视场的大小与视场光阑存在线形关系，同时也受由主镜、目镜组成的放大倍率的影响。

For example, if your widest field eyepiece has a 40mm diameter field stop and you choose a decreasing increment diameter factor of 2 (which results in a 4x decrease in area size), you'll end up with eyepieces having field stop diameters of approximately 40mm, 20mm and 10mm.

例如，如果你的最广视野的目镜拥有40mm的视场光阑直径并且你选择间隔倍率为2，（导致4倍减少区域面积），你最终选择的这组目镜的视场光阑为40mm，20mm和10mm。

Of course, avoid duplicating focal lengths. For example, if you use a 31mm Nagler (with a 42mm field stop diameter), you would not need a 32mm Plossl (with a 27mm field stop diameter).

当然，也要避免焦距重复，例如你使用一个31mm的Nagler (42mm视场光阑)，你不需要一个32mm Plossl (with a 27mm视场光阑)。
