A Single Exposure的意思|示意

The sky in the exposures was de-rotated to compensate for the rotation of Earth, then images were stacked together producing an image identical to a single exposure but with less digital noise.

曝光的天空被旋转着以补偿地球的自转，然后把一连串的图像叠放在一起，产生了与单一曝光相同的图像，可是很少有数码噪声。

Walter Lewin, though, has asked APOD to pose this as a challenge to astrophotographers: create a real single-exposure image of a clear night sky that features 360 degree star trails.

沃尔特·卢因通过APOD向广大天体摄影师发起挑战——拍摄一幅360度星流迹的单曝光晴朗夜空照片。

Immediate effects may show up after a single exposure or repeated exposures.

通过单一或几次的暴露之后，即刻效应便展现出来了。

The time warp occurs because this image captured in a single frame a four hour exposure of the night sky. As a result, prominent star trails are visible.
