The Whirlpool Galaxy  (子持ち銀河) Messier 51,NGC5194,5195

I took this photo about two weeks ago, but I couldn't get the "corner" sticking out to the northwest and the faint dust on the east side.
I divided it into two parts, yesterday, when the seeing was good, and today, and rewatched it from the beginning.
If I add Signal for about 3 more hours, I wonder if I can get more clear dust from the east.

２週間ほど前に撮影したが、北西に向けて飛び出ている”角”と東側にある淡いDustが出せなかったのでSeeingが良かった昨日と今日の２かに分けて撮影からやり直して見た。
もう3時間くらいSignalを追加すると、もっとくっきり東のDustが出せるのかな。
