It is a nebula in the Hii region just east-southeast of the Tulip Nebula. However, this is not very popular, and it seems that the main characters of the saddle region are monopolized by the Crescent Nebula and Tulip.

This nebula captured by Hubble looks just like Eta Carinae, but it seems to be the opposite. Eta Carinae seems to be caused by gas ejected by a suspended star, while Snow Angle is caused by Jet ejected from a newly formed young star affecting surrounding nebulae.

With HOO, I couldn't see the filament inside, but when I shot and edited again with RGBHaOiii, it came out.

To us Japanese, it may most resemble a swimming octopus.

チューリップネブラのすぐ東南東にあるHii領域にある星雲であるが、あまり人気がなく、サドルリージョンの主役は三日月星雲とチューリップが独占という感じであろうか。

Hubbleが写したこの星雲はまるでEta Carinaeとそっくりであるが、成り立ちは正反対の様だ。Eta Carinaeは仮死状態の星が噴き出しておるGasに対して、こちらは出来立ての若い星から噴き出さているJetが周りの星雲に影響してできている様だ。

HOOでは内部のフィラメントはまるで出せなかったが、RGBHaOiiiで撮影・編集し直したら浮き出てきた。

日本人には泳いでいる蛸に一番似ているもしれない。
