The Phantom Frisbee Galaxy (NGC 3079,NGC 3073)

Although it is not a dark galaxy, the background Gradient is terrible due to the influence of PM2.5, and it is difficult to adjust the S / N ratio during editing.
I want a clearer sky.

別に暗い銀河では無いのだが、PM2.5の影響で背景のGradientが酷く、編集時のS/N比の調整が難しい。
もうちょい澄んだ空が欲しいな。
