I looked through the eyepiece eagerly, only to be disappointed. Dang it, he was right.

我急切地把眼睛对准了目镜，结果很失望。该死，他没弄错。

But no sooner had I peered into the eyepiece than the instrument was snatched from my hands.

但我的眼睛还没有挨到镜面上，望远镜就突然被人夺走了。

I still remember seeing Saturn in the eyepiece, a perfect jewel, the rings small but vivid and sharp.

我仍然记得在目镜中看到的土星，一件完美的珠宝，土星环虽小却生动清晰。

And in the image you see him looking through the eyepiece of a state-of-the-art telescope from 1949.

从相片中可以看到，他正通过1949年研发的最先进的望远镜目镜进行观察。

I stooped to the eyepiece and focussed for my vision.

我弯腰，靠近目镜，专我的视野。

In which case, all of the rays passing into your eye from the eyepiece are almost parallel.

在这种情况， 从目镜进入您眼睛的所有光线几行的。

You get maximum magnification when the real image is just barely inside the focal length of the eyepiece. .

当真实图像刚好在目镜焦距内时，您将获得最大放大倍率。

But that can be corrected by using a concave lens for an eyepiece, like Galileo did.

但这可以通过使用 凹透镜作为目镜来纠正，就像伽利略所做的那样。

The user looks into the eyepiece and uses the buttons on the phone to move two lines until they appear as one.

用户看着目镜并使用手机上的按钮移动两条线，直到它们显示为一条线。

This image is very small, but the eyepiece acts as a magnifier, forming a large, virtual image for the observer to view.

这个图像非常小，但目镜 起到放大镜的作用，形成一个大的虚拟 图像，供观察者观看。

You literally stare into an eyepiece and see everything that's in your ear even that crayon you shoved in there when you were five. Still in there.

你可以盯着目镜看，就可以看到耳朵里的一切，甚至你五岁时塞进去的蜡笔。还在里面。

In 1919, when Hubble first put his head to the eyepiece, the number of these galaxies that were known to us was exactly one: the Milky Way.

1919年，当哈勃第一次把脑袋伸向望远镜的时候，我们已知的星系数只有一个：银河系。

Stray light can bounce off of the inside of a telescope and end up in the eyepiece or focuser, which can affect the contrast and ruin the view.

杂光会在镜内不断反射，并最终呈现在目镜或聚焦器上，这种反射不仅会影响对比度，也会破坏观测结果。

After all of the like terms cancel out, you’re left with a magnification equation in terms of the focal lengths of the objective lens and the eyepiece.

在抵消所有类似项后，您将得到一个关物镜和目镜焦距的放大方程。

These mirrors are convex, causing rays to converge into a real image, which is then magnified through an eyepiece or projected directly onto a digital sensor.

这些镜子凸面的，使光线会聚 成真实图像，然后通过 目镜放大或直接投射到数字传感器上。

Prior to the launch of Hubble, when we thought of astronomy and telescopes, we really thought essentially of telescopes on the ground, people looking through eyepieces and things like that.

在哈勃发射之前，当我们想到天文学和望远镜时，我们实际上想到的地面上的望远镜，人们通过目镜之类的东西来进行观察。

Likewise, the tangent of the second angle, theta prime, is equal to the height of the real image over the focal length of the eyepiece.

同样，第二个角的正切 θ素数等 目镜焦距上真实图像的高度。

And the newly subtended angle is the amount that the object subtends when viewed through the eyepiece – the angle between your eye and the rays from the eyepiece.

新的对向角通过目镜观察物体时的对向量——你的眼睛与目镜发出的光线之间的角度。

First described in the early 17th century, the outfit consisted of a hood with crystal eyepieces and a beak filled with a pungent combination of herbs and compounds.

首次描述 17 世纪初，这套装备包括一个带水晶目镜的兜帽和一个充满刺鼻的草药和化合物组合的喙。

The astronomer William Herschel — the same man who discovered infrared light and the planet Uranus — gave them that name, because they appeared like small green disks through the eyepiece.

天文学家威廉·赫歇尔——也发现红外光和天王星的人——给它们取了这个名字，因为它们通过目镜看起来像小小的绿色圆盘。
