The Fishhead Nebula  (フィッシュ・ヘッド星雲) IC1795 ,NGC896

For some reason I can't stand the Heart Nebula and the Soul Nebula, so this nebula was my first target for photography.
I like the composition where I cut off the part below the pectoral fin and rotated 90 degrees counterclockwise.
This way the finer structures stand out, so I made it look like SHO based on Ha, so the Oiii part is narrower than in a normal photo.

なんの理由もないがなぜかハート星雲とソール星雲は生理的に受け付けずこの星雲は初めて撮影のTarget。
胸ヒレから下をバッサリ切って90度半時計回りにした構図が自分では気に入った。
この方が細かい周辺の構造が浮いてくるのでHaをベースにSHO風にしたので普通の写真よりOiii部分は狭くなっている。
