As one of the most often used mountings, the altazimuth mounting satellite tracker has a blind area near the zenith because of the very high azimuth angular velocity, as a result, discontinuous observing data are caused. As for those fast flying satellites, this kind of blind area is very significant because it causes difficulties in precisely determining the satellites' orbits.
作为最常用的一种机架，采用地平式机架的人卫跟踪仪在观测天顶附近区域的目标时，由于方位转速过大而不能连续观测，存在一个固有的天顶盲区，特别是对飞行速度较快的近地卫星，这个盲区的影响是相当大的。

Over in the west there was the last of the night, and in the east, to the windward, the first of day; and there, clear against the lightening sky, lay a vessel, already quite near, a very large two-masted double hulled canoe with a broad platform or deck overlapping the hulls with a thatched house upon it; and the vessel had two towering fore and aft sails, each with a curved crest reaching forwards.
在西面是黑夜的最后残余，在东面、在顶风的方向，则是一天的开始；而在那儿，在渐渐变亮的天空背景下，可以清楚地看见一艘海船，离他们已经很近了，那是一条很大的双桅杆、双船体的木舟，带有宽阔的平台或者甲板，平台覆盖在两个船身上面，平台上有座草顶的木屋；这条船扯着两面高高的前后帆，每一面帆都有朝前弯曲的冠顶。

The results showed that the red /blue color index during twilight changed evidently with AODs in lower atmosphere. When AOD was small, there was a maximum of the radiance at 450nm in the high view elevation angle. So the sky color at the zenith is blue. However, the maximum shifted to red wavelength (about 700nm) with the fall of view elevation angle.
计算结果分析表明，曙暮光时天空辐射强度的红蓝光颜色指数随近地层大气气溶胶光学厚度的变化显著；当τ较小时，太阳辐射随波长的变化显著，在高仰角450nm附近有极大值，天顶方向以蓝色调为主；而在低仰角极大值向红光方向移动。

eyepiece：目镜
天文望远镜的效能除了大部份受物镜或主镜影响之外,目镜(EYEPIECE)也不可以忽视. 除了牛顿反射镜可以方便观测者作天顶观测外,大多的望逮镜当要观看近天顶的天区时都会显得不方便. 天顶棱镜就是利用一个棱镜(PRISM)将望远镜光轴反射9 0度方便观测.
