The Triangulum Galaxy  (三角座の銀河) Messier 33

I've shot this target every year for three years, but I've always been invaded by a terrible gradient and kept losing.
For the first time, I was freed from gradient attacks, and I was able to edit honestly.
I wanted to add Ha, but the Red channel had some Hii areas, so I simply changed the Pallete to RGB.

3年間毎年このターゲットを撮影したが、必ず酷いGradientに侵され、負け続けてきた。
今回初めてGradient攻撃から解放され、素直な編集ができた。
Haを加えようと思ったが、RedチャンネルにそこそこHii領域があったので、Palleteも素直にRGBにした。
