It's the eyepiece of the biggest microscope in the world.

它是世界上最大的显微的目。

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，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.

我的眼睛还没有挨到面上，望远就突然被人夺走了。

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年研发的最先的望远目观察。

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

我仍然记得在目中看到的土星，一件完美的珠宝，土星环虽小却动清晰。

I stooped to the eyepiece and focussed for my vision.

我弯下腰，靠近目，专注于我的视野。

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

这可以通过使用 凹透作为目来纠正，就像伽利略所做的那样。

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焦距内时，您将获得最大放大倍率。

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

在这种情况下， 从目入您眼睛的所有光线几乎是平的。

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，目 起到放大的作用，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.

你可以盯着目看，就可以看到耳朵里的一切，甚至你五岁时塞去的蜡笔。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.

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

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素数等于 目焦距上真实图像的高度。

While Galileo used a concave lens for his eyepiece, the standard refracting telescope uses a convex, converging lens for both the objective lens and the eyepiece.

伽利略的目使用凹透，而标准折射望远的和目都使用凸透。

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, 当哈勃第一次把头伸向目时, 我们已知的这些星系的数量恰好只有一个 - - 银河系。

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，您将得到一个关于和目焦距的放大方程。

And just like with telescopes, the real image is just inside the focal point of the eyepiece, generating a large virtual image for the observer to view.

就像望远一样，真实图像 就在目的焦点内，成 一个大的虚拟图像供观察者观看。

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时，我们实际上想到的是地面上的望远，人们通过目之类的东西来观察。
