Survey Shot Eagle Nebula

I shoot every year, but the result is halfway, so I thought I'd finish it to a level that I could be satisfied with during the remaining time of this season and the first half of next season (late October), so I had a total of 1 hour before dawn. I took a test shot.
The challenge is
-Increase the total exposure time as much as possible to eliminate the roughness of the background.
-Make Target more Sharp.
-Make the small eagle more transparent.
-Make the banner under the wings of the Small Eagle more visible.

毎年撮影してるが中途半端な結果に終わってるので、今シーズンの残り時間と来シーズンの前半(10月後半)のこれが見えてる期間で自己満足できるレベルに仕上げようと思い、夜明け前にTotal1時間ほどテスト撮影してみた。
課題は
O極力Totalの露出時間を増やして背景のザラザラを無くす。
OTargetをもっとSharpに。
Oスモール・イーグルをもっと透明に近くする。
Oスモール・イーグルの羽根の下の垂れ幕をもっとはっきり見えるように。
