The Swan Nebula A.K.A Omega Nebula (スワン星雲) Messier 17

I got a Crazy Clear Sky that I could see the Milky Way with the naked eye from the Backyard of Boltle6 for about an hour, so I turned the telescope on the swan.
Like Eastern Veil Nebula , the central spine of this nebula is unusually bright, and even the 2-minute exposure of Ha is nearly overexposed.
When compositing, Ha was blended to 25% of Oiii and Sii, and HDR processing was applied during editing, making it possible to see it somehow.
I didn't like the red swan, so I used SHO as the basic palette and made adjustments for each color, and ended up with a chicken. No matter how you look at it, it looks nothing but Northern Running Chicken.Lol

1時間ほどBortle6のBackyardから肉眼で天の川が見えるほどのCrazy Clear Skyを手に入れたので、白鳥に望遠鏡をむけてみた。
この星雲もVeil星雲東と同様に中心部の背骨が異常に明るく、Haは2分の露出でもその部分は露出オーバー気味になってしまった。
コンボジット時にHaはOiiiやSiiの25%のブレンド量にして、編集時にHDR処理をかけてなんとか見られる様になった。
赤い白鳥はイマイチと思い、SHOを基本パレットに色毎に調整をしていたら、完全に鶏になってしまった。どう見てもNorthern Running Chicken にしか見えないなー。hahahaha
