Solar filters designed to thread into eyepieces that are often provided with inexpensive telescopes are also unsafe 廉价望远镜附设可扭上目镜的太阳滤镜也是不安全的
The increased image scale allows for imaging without an intervening eyepiece - - like in prime focus photography 增加的意象尺度允许成像没有介入目镜-像在首相焦点摄影。
The resulting image at the eyepiece diaphragm level is actually a mosaic of airy disks which you perceive as light and dark 最终在目镜光栏面上获得的成像实际是一个镶了边的艾利斑。
The eye lens of the eyepiece further magnifies this image which finally is projected onto the retina or the camera film 目镜的接目镜再将这个图像投射到人眼的视网膜或照相机的胶片上。
Planets should be highly magnified with the eyepiece projection method before their disks or surfaces could be recorded 行星必须通过高倍放大才能拍摄到其表面特徵。拍摄时对焦必须十分准确。
As the converted photons strike a phosphorus screen as electrons , they are perceived through an eyepiece in shades of green 这样，戴上一种绿色的目镜就可以看到由这种电子在磷屏幕上形成的影像。
After taking the d1 ( d2 ) from eyepiece micrometer and entering them , the hardness value is displayed on lcd and the data can be printed out 输入用测微目镜测得的对角线长度,即在lcd上显示硬度值。可打印记录。
After taking the d1 ( d2 ) from eyepiece micrometer and entering them , the hardness # 118alue is displayed on lcd and the data can be printed out 输入用测微目镜测得的对角线长度,即在lcd上显示硬度值。可打印记录。
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，不仅会加剧问题，因为射线路径进入目镜是陡峭。
