RCW 27 Nebula (RCW 27) WMBNC 15

WMBNC 15: Catalog of large nebulae in the winter Milky Way 15
RCW27 is the northernmost object of three RCW nebulae lined up next to each other to the northwest of the famous Pencil Nebula.
It is surrounded by the surrounding Ha interstellar clouds, so the whole thing is bright red, which is amazing.

このRCW27は有名なペンシル星雲の北西に3つほど隣り合わせに並ぶRCW星雲の一番北のObject、
周辺のHaの星間雲に包まれているので、全体が真っ赤ですごいな。
