The constellation of Orion is much more than three stars in a row. It is a direction in space that is rich with impressive nebulas. To better appreciate this well-known swath of sky, an extremely long exposure was taken over many clear nights in 2013 and 2014. After 212 hours of camera time and an additional year of processing, the featured 1400-exposure collage spanning over 40 times the angular diameter of the Moon emerged. Of the many interesting details that have become visible, one that particularly draws the eye is Barnard’s Loop, the bright red circular filament arcing down from the middle. The Rosette Nebula is not the giant red nebula near the top of the image — that is a larger but lesser known nebula known as Lambda Orionis. The Rosette Nebula is visible, though: it is the red and white nebula on the upper left. The bright orange star just above the frame center is Betelgeuse, while the bright blue star on the lower right is Rigel. Other famous nebulas visible include the Witch Head Nebula, the Flame Nebula, the Fox Fur Nebula, and, if you know just where to look, the comparatively small Horsehead Nebula. About those famous three stars that cross the belt of Orion the Hunter — in this busy frame they can be hard to locate, but a discerning eye will find them just below and to the right of the image center.

🌌 在冬季的星空中，獵戶座不僅僅是三顆星星排成一行的簡單安排，它是一個充滿瑰麗星雲的空間。為了更好欣賞這片著名的天空，2013年至2014年間拍攝了一個極長的曝光，總共212小時的攝影時間，加上一年後期處理，最終呈現出這幅獨特的1400幅曝光合成圖，跨越超過40倍月亮的視角直徑。
🔴 在這幅圖中，非常引人注目的細節之一是巴納德環（Barnard’s Loop），它是一條明亮的紅色圓形絲帶，從畫面中央向下彎曲。上部的較大卻不太知名的星雲是藍色獵戶星雲（Lambda Orionis），而真正的玫瑰星雲（Rosette Nebula）則位於上左方，閃耀著紅白色的光芒。
✨ 画面中央稍上方的明亮橙色星星是貝特魯斯（Betelgeuse），而下右方的亮藍色星星是瑞吉爾（Rigel）。此外，還能看到其他著名的星雲，包括女巫頭星雲、火焰星雲、狐狸毛星雲，以及如果你仔細尋找的話，還能找到比較小的馬頭星雲。
⭐️ 而那三顆橫越獵戶之腰的明亮星星，在這繁忙的畫面中可能難以定位，但用心的你一定能在畫面中央下方稍右的位置找到它們。
