  调整右目镜（图1序号3），以获得与操作者视力相适应的视度，获得清晰的图像。

• the method i developed requires no eyepiece and no control of the ra axis movement.

  小弟开发的方法，不需要接目镜，也不用可以控制赤经轴的移动。

• after focusing, slip the viewfinder cap attached to the strap over the viewfinder eyepiece as necessary.

  对焦后，必须将背带上的目镜盖插入取景器目镜上。

• dave, we hope you're not looking through the eyepiece of your telescope when sweeping through the sky for this galaxy.

  大卫，我们希望你在天空中找这个星系的时候不是通过望远镜的目镜来寻找的。

• when viewing extended objects, the apparent brightness seen in the eyepiece is a function only of aperture and magnification, it is not related to focal ratio.

  当观察扩展光源时，目镜中所看到的亮度只跟孔径和放大率有关，它跟焦比并没有关系。

• the compound microscope consists of two convex lenses with short focal length, the objective and eyepiece lenses, fitted at opposite ends of a tube.

  复合显微镜包括两个短焦距凸透镜，即位于镜筒两端的物镜和目镜。

• an eyepiece with wide apparent field (in degrees) and lower powers used on a telescope allow wider fields of view.

  较宽的目镜视场搭配较低的放大率可以得到更宽的视场角。

• and having a screen in the eyepiece gives you all kinds of advantages you don’t get when you’re just looking through glass.

  再配上接目镜，让你拥有透过光学取景器取景所无法比拟的优势。

• for example, if you were using an eyepiece with a 50 degree apparent field, and the power of the telescope with this eyepiece was 100x, then the field of view would be 0.5 degrees (50/100 = 0.5).

  比如，你的目镜有50度的视场，望远镜的放大率为100，那么视场将是0.5度(50/100 =0.5)。

• or, you can calculate the exit pupil by dividing the focal length of the eyepiece (in mm) by the focal ratio of the telescope.

  或者，你还可以将目镜的焦距除以望远镜的焦比来得到出瞳尺寸。

• to determine power, divide the focal length of the telescope (in mm) by the focal length of the eyepiece (in mm).

  将望远镜的焦距(单位:mm)除以目镜的焦距(单位:mm)，就可以得到望远镜的放大率。

• the right for the standard color, optical eyepiece with light regulation and focusing ability, easy to use.

  其右边的为标準色颜色，光学目镜具有光线调节和调焦能力，使用方便。

• after range finding, 「0000」 displayed on displayer on the upside of right eyepiece indicates no laser, reasons may.

  当测距之后，左目镜上排显示器显示「0000」 ，表示无激光。产生无激光原因是。

• the thin 20-ounce computer drapes across your torso, sending information to an eyepiece that simulates the view of a 14-inch screen.

  这种重20盎司的薄薄的电脑可以缠在你的胸部，把信息传递到一个目镜，而目镜能模拟一个14英寸的显示屏显示的图像。

• the exit pupil of a telescope is the circular beam of light that leaves the eyepiece being used and is measured in mm.

  望远镜的出射光瞳是指射出目镜的圆形光束的直径，单位是mm。

• for example, an 8" aperture telescope (203mm) used with a 20mm eyepiece is working at 102 power and has an exit pupil of 2mm (203/102 = 2mm).

  比如，带有20mm目镜的孔径为8英寸(203mm)的望远镜的放大倍数如果为102，那么它的出瞳则为2mm(203/102 =2mm)。

• power, or magnification, of a telescope is actually the ratio between two independent optical systems – (1) the telescope itself, and (2) the eyepiece (ocular) you are using.

  望远镜的放大倍数其实就是两个独立的光学系统的比值-(1)望远镜本身(2)以及所使用的目镜。

• to calculate exit pupil, divide the aperture (in mm) by the power of the eyepiece being used.

  为了计算出射光瞳，可将孔径(单位mm)除以目镜的放大倍数。

• the picture is taken vibration-free by pressing a button on the remote control. without disturbing you can continue looking through the eyepiece to the image.

  该图片是采取无振动按下一个按钮，按遥控器上的控制。而不干扰你可以继续期待透过接目镜到图象。
