RCW 38,39,40 (RCW 38,39,40) WMBNC 19

WMBNC 19: Catalog of large nebulae in the winter Milky Way 19
The large nebula at the top of the photo is the main target, RCW 38. However, since I had enough space in the angle of view, I also included RCW 39 and 40 in the field of view.
This area is also attractive because of the blue gas.

WMBNC 19: 冬の天の川の中にある大きな星雲のカタログ19
写真上の上にある大きめの星雲がRCW 38がメインターゲット。ただ画角に余裕があったので一緒にRCW39,40も写野に入れて見た。
この辺は青いガスもあって魅力的だな
