Whether good or bad, a comment about the temperature or sky condition (sunny day, cloudy day, rainy day, etc.) never offends.

谈论气温或天候（晴天、阴天、雨天等），评语不论是好是坏，永远都不会得罪人。

Trying to observe faint galaxies under bright sky conditions is like trying to listen to someone 50 feet away whispering at you at a rock concert.

试图在明亮的天空下观察暗淡的星系，就好比在摇滚音乐会上试图听一个50英尺外的人对你的低语。
