It also flips left and right, which can be a little disconcerting, and takes getting used to when you're using a refracting telescope.

它也是左右颠倒的，这可能会让人感到不适，所以当使用折射望远镜时，你需要花一点时间适应。

Refracting telescopes are great, but they suffer from a big problem: big lenses are hard to make.

折射望远镜很棒，但有一个致命缺陷：大型透镜很难制造。

Galileo pioneered the use of refracting telescopes in astronomy.

伽利略率先在天文学中使用折射望远镜。

Then, we analyzed how refracting telescopes and compound microscopes function using the same principles.

然后，我们分析了折射 望远镜和复合显微镜 如何使用相同的原理发挥作用。

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.

伽利略的目镜使用凹透镜，而标准折射望远镜的物镜和目镜都使用凸透镜。
