The Fuzzy Butterfly Cluster (ファジー・バタフライ<蛾>散開星雲) NGC 654 

Since it is a star cluster in the Milky Way in autumn, there are many surrounding stars and it is beautiful, but LRGB was a failure.
I think the stars would have been more beautiful if I had used only RGB in a 60 second Sub Frame.

60秒くらいのSub FrameでRGBだけでまとめた方が星がもっと綺麗だった気がする。
