RCW 19,20 Nebula (RCW 19,20) WMBNC 14
WMBNC 14: Catalog of large nebulae in the winter Milky Way 14
This catalog has also entered the deep southern sky.Speaking of the southern sky, RCW is famous for its counterpart to the northern SH2 catalog.
This catalog has already shared RCW objects that form part of the Seagull Nebula and the Skull and Crossbones Nebula, but I plan to photograph a few more RCW objects from here on out.
Many of these are located inside bright red molecular clouds, so the red world will continue from here on out.
The large nebula in the center is RCW19, and the smaller nebula to the left is RCW20.
RCW19 looks somewhat like the Pac-Man Nebula. RCW20 looks like the head of the Seagull Nebula. The group of blue stars just below and to the right of RCW20 is vdb-Ha 23.
WMBNC 14: 冬の天の川の中にある大きな星雲のカタログ14
このカタログもDeepな南天に入ってきた。南天と言えば北天のSH2カタログに対するRCWが有名である。
このカタログでもすでにかもめ星雲の一部を構成するRCWやSkull and Crossbones 星雲のRCW天体をシェアしているがここからも数枚ほどRCW天体を撮影予定。
これらは真っ赤な分子雲の中にあるものも多いので、この後赤い世界が続くことになる。
中央の大きい星雲がRCW19,左隣の小さい星雲がRCW20。
RCW19は何となくPac-Man星雲に似てる。RCW20はかもめ星雲の頭の部分に似てるな。RCW20のすぐ右下にある青い星のまとまってるところがvdb-Ha 23。
