Ok. The view is blurry. How do I focus the camera?

好的。视野很模糊，我该怎么聚焦呢？

I chose the break beam as opposed to the PIR sensor because its straight break line makes for an easier place to focus my camera.

我选择了断光束而不是 PIR 传感器，因为它的直线断线使我的相机更容易对焦。

It's a picture taken by the Hubble Space Telescope over a period of eleven days and it focused its camera on the tiniest piece of sky just below the constellation of Orion.

为了拍摄它，哈勃望远镜总共花了 11 天时间将镜头对准了猎户座下方的一小块区域。
