Twin Quasar (2重クエーサー)Q0957+561 A/B

Mr.Tsukuda, a senior Japanese astronomer, commented on a recent post by Phantom Frisbee Galaxy, saying, "There is a double quasar nearby, I could see it with a 50cm mirror before." Thank you. I decided to shoot without waiting for the clear sky.
According to the information on the NASA site, these two quasars are actually one quasar whose light is bent by the intense gravity of the galaxy in the foreground due to the gravitational lens effect, and it splits into two and jumps into our eyes. Is. In other words, these two quasars are exactly the same.
It seems that B arrives at our eyes about 1.1 light-years later (detour) than A.
The distance from us is about 14 billion light-years, and the light that is arriving now is the light that shined 9 billion light-years ago. About 14 billion light-years ... It was around the time of the birth of the universe. It is a celestial body far enough to die. I never thought I could shoot such a distant thing with an amateur telescope.
The gravitational lens was predicted by Einstein, and the first celestial body to prove it is this Q0957 + 561 A / B.
I never dreamed that the effect of gravitational lenses would catch photons that had traveled 9 billion light-years. I've never been so happy.
Tsukuda-san, thank you very much for the information.

先日のPhantom Frisbee Galaxyの投稿に日本の天文家の大先輩である佃さんがコメントで、「その近くに2重クエーサーがあるよ〜、私は以前50cm鏡で眼視できたよ〜」と教えてくださった。快晴の空を待てずに撮影決行。
重力レンズはアインシュタインが予言したが、その証拠となる最初の天体がこのQ0957+561 A/Bである。
