The Small Cluster Nebula (小さな星団星雲）NGC7129

As the name suggests, the nebula spreads around a small star cluster.
Another name is the Rosebud Nebula. It certainly looks like that.
It is located just southwest of Iris Nebula, in the constellation Cefaus.
Iris Nebula is so famous that it has been overshadowed, but I think it is a very beautiful nebula.
Approximately 130 of the star clusters inside are said to be around 1 million years old. So young~~~~

名前の通り小さな星団を包み込むように星雲が広がっている。

別名は薔薇の蕾星雲。確かにそう見える。

場所はIris Nebulaのすぐ南西にあり、ケファウス座に位置する。

Iris Nebulaがあまりにも有名ため影を潜めているが、なかなか綺麗な星雲だと思う。

中にある星団はのうち130個くらいは100万程度の年齢だそうだ。若いな〜〜〜
