The Tail Shape of Comet C/2023 A3 Tsuchinshan-ATLAS  (C/2023 A3の尾の様子)

I wanted to see it in RGB, but unfortunately clouds appeared when I was halfway through shooting.
If I include stars in the photo, I can't take another photo the next day, and even if I take a starless photo, the comet itself is constantly changing, so it would be strange to take another photo the next day.
So I decided to make do with B and R, which only managed to pick up SIganal for half the planned exposure time.
I confirmed from a photo by my old friend Cristian Suciu from Romania that the line extending into the tail is not an editing error, but is actually there.

RGBでみて見たかったが、残念ながら半分撮影したところで雲のお出まし。
星入りの写真にすると次の日に撮り増しはできないし、スターレスにしても彗星自体がどんどん変化してるので、やはり次の日の撮り増し対応はおかしなことになる。
よってBと予定露出時間の半分しかSIganalを拾えなかったRでなんとすることに。
この尾の中に伸びる線は編集ミスではなく、実際にあることを古くからの友人のルーマニアのCristian Suciuさんの写真で確認した。
