[漢羅] 大蝎虎星雲 ê 雲波

大蝎虎星雲是天頂上大 ê 星雲之一，是講咱以前哪會無啥注意著？ 伊 kah 仙女座星系 ê 角寸尺差不多平大，咱會當 tī 四跤蛇星座（蝎虎座） 揣著伊。 咱若是用雙筒千里鏡，欲揣 發射星雲 是有較困難，因為伊 足暗--ê。 毋閣就算是用大型天文望遠鏡嘛真歹揣，因為伊 ê 角寸尺傷大矣，差不多有 3 度 闊。 這个星雲去 hŏng 編做是 Sharpless 126 (Sh2-126)，伊 ê 深度、闊度、雲波、kah 美麗，會當利用 kha-mé-lah 長時間感光 kā 翕落來欣賞。 這是一張組合相片，是 kā 今年六、七月彼陣 tiàm 西班牙 IC 天文台 開 6 暗 ê 時間，用 5 種無仝色光 ê 濾光片，攏總翕 10 點鐘久 ê 時間，疊出來 ê 影像。 Tī 大蝎虎星雲內底 發紅光 ê 水素 氣體，是去予 蝎虎座 10 這粒足光 ê 恆星激發--ê。 伊就 tī 這个發紅光 ê 星雲中央，彼粒上光 ê 藍光星。 這寡恆星 kah 星雲 離咱有 1200 光年 遠。

[English] Waves of the Great Lacerta Nebula

It is one of the largest nebulas on the sky -- why isn't it better known? Roughly the same angular size as the Andromeda Galaxy, the Great Lacerta Nebula can be found toward the constellation of the Lizard (Lacerta). The emission nebula is difficult to see with wide-field binoculars because it is so faint, but also usually difficult to see with a large telescope because it is so great in angle -- spanning about three degrees. The depth, breadth, waves, and beauty of the nebula -- cataloged as Sharpless 126 (Sh2-126) -- can best be seen and appreciated with a long duration camera exposure. The featured image is one such combined exposure -- in this case 10 hours over five different colors and over six nights during this past June and July at the IC Astronomy Observatory in Spain. The hydrogen gas in the Great Lacerta Nebula glows red because it is excited by light from the bright star 10 Lacertae, one of the bright blue stars just above the red-glowing nebula's center. The stars and nebula are about 1,200 light years distant.
