2022年9月14日 · 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 ...

2022年1月4日 · Image Description and Details : Sharpless 126 (Sh2-126) is the designation of a large emission nebula in Lacerta, which appears in this image as a red background and exceeds the edges of the image. The source of its ionization is the intense ultraviolet radiation from the star 10 Lacertae, a blue main sequence star.

2016年8月29日 · Sharpless 126 is a huge but faint emission nebula in Lacerta. This is a small portion of it. The source of its ionization is the intense ultraviolet radiation of the star 10 Lacerta which is not seen in this FOV and is off to the left.

In southern region of Lacerta, it's an extraordinary dimmed and large H-alpha nebulosity lying in the outskirts of Milky Way. The elusive autumnal object consists of a reddish filament structure with a length of over 3 degrees and color-less thin streaks distributed in northern part, of course we cannot detect the nebula with our naked eyes.

This is a 3-panel mosaic of Sh2-126, the Great Lacerta Nebula, imaged in HOO and rendered using a Power-of-Inverted-Pixels technique. Total integration time is just under 52 hours, captured over 18 nights in December and January.

2024年10月13日 · カメラレンズの短焦点の明るいレンズは CMOS カメラではピントが中々決まらないと星友が教えてくれた。 このSh2-126は非常に淡く、これまで何度も撮影したが綺麗に撮れなかった。 今日は時間をかけてこれ一本に絞って撮影した。 月没後はフィルターを交換して撮影したが、急に雲が湧き出し晴れたり曇ったりの不安定な天候になってしまい半分以上が没 (-_-;)。 撮影日時、場所：2024年10月11日 19:00～ 愛知県旭高原元気村周辺. 撮影機 …

撮影メモ： とかげ座の南部，秋の天の川からやや南に外れた領域に広がる極めて淡い散光星雲です。 南北の長さが3度強ある，赤いHα光を発する筋状の構造と，その北側の極めて淡い分子雲の流れからなっており，もちろん肉眼で見ることはできません。 この星雲の周辺には星団とは呼べないものの，明るい星がまばらに分布しており，「とかげ座OBアソシエーション」と呼ばれています。 ※この写真は焦点距離180mm相当にトリミングしています。 御意見，御感想をお …

Sh2-126 is an emission nebula located in the Lacerta constellation. It is located in the southern part of this constellation, about 1° west of the star 10 Lacertae, a blue variable star (magnitude 4.8 and spectral type O9V) which ionizes the nebula.
