The plan was to capture a picturesque part of the sky that was hosting an unusual guest. The result included a bonus — an additional and unexpected guest. The beautiful background features part of the central band of our Milky Way galaxy on the far left, and the colorful clouds of Rho Ophiuchi in the image center. The unusual guest, a dimmed and reddened Moon on the right, was expected because the image was taken during last week’s total lunar eclipse. The timing had to be right because the Moon — both before and after eclipse — would be so bright it would overwhelm the background. The unexpected guest was the bright meteor across the image center. The fleeting meteor streak was captured on only one of the 10 consecutively-captured deep-field images from La Palma in the Spanish Canary Islands, while the eclipsed Moon image was taken immediately afterwards with the same camera and from the same location. The next total lunar eclipse — also quite expected — will occur in early November. 

计划是捕捉天空中一个风景如画的部分，那里有一位不同寻常的客人。结果另外得到了奖励——一位额外的意外客人。最左侧银河系中央带的一部分是美丽的背景，图像中心是五颜六色的蛇夫座星云。这张不寻常的照片是在上周的月全食期间拍摄的，因此人们预计这张照片的右侧是一个暗红色的月亮。时间必须是正确的，因为月食前后的月亮都会非常明亮，会淹没背景。意外的客人是穿过图像中心的明亮流星。在西班牙加那利群岛拉帕尔马连续拍摄的10张深场图像中，只有一张捕捉到了短暂的流星条纹，而月蚀图像随后立即用相同的相机在相同的位置拍摄。下一次月全食也很有可能发生在11月初。
