The Proxima Centauri aka Alpha Centauri-C (プロキシマ・ケンタウリ) Closest Star From Our Earth
the closest star to earth
Proxima Centauri is the third of the triple stars Alpha Centauri.
It is the closest star to Earth, about 4 light years away.
Since it is a triple star, I thought it was close to Alpha Centauri-A, which is a 1st magnitude star, but it is far away. I have no idea why this star was judged to be one of the triple stars of Alpha Centauri.
If you try to put Alpha Centauri-A and Proxima in the same FOV, even a full-size sensor can only be captured with a telescope with a focal length of 700mm or less.
There was a request from a friend, and since it is difficult to capture it from the northern hemisphere unless it is south of Thailand, I took it.
The large orange star in the center (11th magnitude) is Proxima.

地球に一番近い恒星
3重星のアルファ・ケンタウリの3番目がこのProxima Centauri星。
約4光年離れた地球から一番近い恒星である。
3重星と言うことなので1等星のAlpha Centauri-Aに接近しているのかと思いきや、なんととてつもなく離れていて、なぜこの星がAlpha Centauriの3重星の一つと判断できたのかさっぱりわからない。
もしAlpha Centauri-AとProximaを同一FOVに収めようとするとフルサイズのセンサーでも700mm以下の焦点距離の望遠鏡でないと写せない。
友人からのリクエストもあり、尚且つ北半球からはタイより南でないとなかなか写せないので撮ってみた。
中心の大きなオレンジ色の星(11等星)がProximaである。
