星星(点光源)的亮度只是望远镜孔径的函数-孔径越大，图像越亮。
The brightness of stars (point sources) is only a function of telescope aperture-the larger the aperture, the brighter the images.
这是指望远镜的焦距与其孔径的比值。
This is the ratio of the focal length of the telescope to its aperture.
对于任何放大率的望远镜，孔径越大，其成像亮度越高，成像边缘越锋利。
At any given magnification, the larger the aperture, the brighter and sharper the image will be.
比如，孔径为8英寸的望远镜的边缘亮度是14.0 (7.5 + 5LOG 20.32 = 7.5 + (5x1.3) = 14.0)。
For example, the limiting magnitude of an 8" aperture telescope is 14.0. (7.5 + 5 LOG 20.32 = 7.5 + (5x1.3) = 14.0).
古德说这些图像由大熊湖天文台的1.6米通光孔径离轴新型太阳天文望远镜拍摄。
Goode said that the images were achieved with the 1.6 m clear aperture, off-axis New Solar Telescope (NST) at BBSO.
当真正的数据来自于某些像18米孔径的空间望远镜时，天体生物学家将无从解释，而且永远也不能达成共识。
And when the real data trickle in from something as big as an 18-meter aperture space telescope, astrobiologists will be befuddled interpreting it. They may never reach a consensus.
这不是星星自身的光环，而是由于望远镜的圆形孔径光阑以及光的物理特性造成的。
This is not the star's disk you are seeing but the effect of having a circular aperture in your telescope and due to the nature of light.
望远镜的孔径越大，该设备分辨率就越好，前提是该望远镜的光学设计良好。
The larger the aperture of a telescope, the more resolution the instrument is capable of, assuming the telescope optics are of high quality.
三周后，用坐落在蒙那亚克山上的凯克天文台的十米级望远镜、哈勃太空望远镜以及其他的大孔径望远镜可以证认候选体的特性。
The three-week delay guaranteed that he could confirm and characterize the candidates at the 10-m telescope at the Keck Observatory on Mauna Kea, the HST, or another powerful telescope.
比如，孔径为60mm(即2.4英寸孔径)的望远镜最大放大率为142x。
For example, the maximum power on a 60mm telescope (2.4 "aperture) is 142x."
