原文:
Have you ever seen the Pleiades star cluster? Even if you have, you probably have never seen it as dusty as this. Perhaps the most famous star cluster on the sky, the bright stars of the Pleiades can be seen without binoculars from even the depths of a light-polluted city. With a long exposure from a dark location, though, the dust cloud surrounding the Pleiades star cluster becomes very evident. The featured exposure took over 12 hours and covers a sky area several times the size of the full moon. Also known as the Seven Sisters and M45, the Pleiades lies about 400 light years away toward the constellation of the Bull (Taurus). A common legend with a modern twist is that one of the brighter stars faded since the cluster was named, leaving only six stars visible to the unaided eye. The actual number of Pleiades stars visible, however, may be more or less than seven, depending on the darkness of the surrounding sky and the clarity of the observer’s eyesight.

🌌 你見過昴宿星團嗎？即使你見過，你可能從未見過這麼多灰塵的樣子。昴宿星團（Pleiades），又名七姐妹（Seven Sisters）或 M45，係天際上最著名的星團之一，甚至喺光污染嚴重嘅城市中都能夠裸眼觀察到佢嘅明亮星星。不過，若在黑暗地點進行長時間曝光，圍繞昴宿星團的塵埃雲就變得非常明顯。呢張專輯攝影作品進行了超過12小時嘅曝光，覆蓋了幾倍於滿月的天空範圍。
昴宿星團距離地球大約400光年，位於金牛座（Taurus）方向。關於昴宿星團有一個常見傳說，經過現代化的轉述，就是由於其中一顆較亮的星星逐漸黯淡，讓裸眼只看到六顆星星。根據周圍天空的黑暗程度和觀察者的視力清晰度，實際上可見的昴宿星星數目可能會多於或少於七顆。
