The Markarian’s Chain (M84,M86,NGC4477, NGC4473, NGC4461, NGC4458, NGC4438,NGC4435)
Even though it is the middle of the galaxy season, I have only managed to take one picture of Andromeda as a single galaxy this year with a short focal length. I finally managed to take a picture of the Markarian's Chain yesterday, which I wanted to photograph while using the short focal length setting.
I have been photographing it from Pattaya every year, but the results were not what I expected, so I wanted to photograph it under a better sky.
I was able to pick up the amount of light I wanted in terms of brightness, but for some reason the Image Solver did not work and I could not use SPCC. Therefore, I performed a normal color calibration, but I feel like something is not right.
Since I could not get the correct colors, I shifted the stars quite a bit to blue so that the galaxy and the stars could be clearly distinguished.
The objects that make up this cascade of galaxies are eight galaxies,
M84,M86,NGC4477, NGC4473, NGC4461, NGC4458, NGC4438,NGC4435
and are located about 50 to 55 million light years away from Earth.
Attach screenshots of the galaxies that make up the cascade in the comments section.

銀河のシーズンのど真ん中なのに単体での銀河は今年はまだ短焦点でアンドロメダを一枚撮影しただけだ。短焦点のセッティングのうちに撮影したかったMarkarian's Chainがやっと昨日撮影できた。
毎年パタヤから撮影していたが、思う様な結果でなかったので、より良い空の下で撮影したかった。
輝度的には思うよな光量を拾えたが、なぜかImage Solverが働かず、SPCCが使えない。よって普通のカラー・キャリブレーションを行ったがなんか違うが気がする。
正しい色が出せないのであればということで、星はかなりBlueにシフトさせて銀河と星を明確に区別できる様にして見た。
