The Centaurus A Galaxy (ケンタウルス座A銀河) NGC5128

The 50% perfect circle core part from the center is very bright and can be photographed fairly well with a 2 hour exposure, but
The Halo part from that point on was extremely light, and I ended up adding another 4 hours and 30 minutes, resulting in an exposure of 6 hours and 30 minutes. However, I think the charm of amateur photography of this galaxy is the dark band in the center and the elliptical core that seems to dissolve into space. Unfortunately, it seems impossible to create a jet of radio waves extending from northeast to southwest. (I feel like I can somehow capture a part of the northeast jet edge)
Lately, even when the weather is sunny, the PM2.5 makes the sky shift to red, as if I were wearing a camera lens filter.
I tried to make it as vivid as possible.

中心から50%の真円のコアの部分はとても明るく2時間の露出でそこそこ写るが、

そこから先のHaloの部分は極端に淡く、もう4時間30分追加することになり6時間30分の露出になってしまった。しかしこの銀河のアマチュア撮影の魅力は中心部の暗黒帯と宇宙にの空間に溶けていくような楕円のコアだと思う。北東ー南西に伸びる電波のジェットは残念ながら無理なようだ。（北東のジェットの端の一部はなんとか撮れる感じ）

最近晴れてもPM2.5の影響でカメラのレンズフィルターを装着してるみたいに赤にシフトしてしまう。

いっそのことビビッドにしてみた。
