The Supernova Remnant at Lobster Nebula (超新星残骸@ロブスタ星雲) SNR G353.2+00.9

Well, I thought it would be relatively easy to show the internal structure of the object because it was a bright subject, but it was too bright and it was difficult to bring out the contrast.
As a result, it became a level of investigating the structure by sharpening the blur as much as possible.
Because of the forced exposure, there was a lot of noise, and even with all kinds of NR, it wasn't a perfect match, and I ended up focusing more on the noise than the Target.
For the time being, in order to make the part that I want to see first, I ended up blurring the part with severe noise in Local units. It may be the last line for astronomical photography.

いやー、明るい対象なので比較的内部構造を簡単に出せるかなと思っていたが、その逆で明るすぎてコントラストを出すのが難しかった。
結果としてモヤモヤを極力シャープにして構造を調査するレベルになってしまった。
無理やりに近い露出をしているので、酷いノイズがあり、ありとあらゆるNRを使っても完璧には太刀打ちできず、Targetよりノイズに目がいってしまう状態になってしまった。
とりあえず見たい部分に最初に目が行くレベルにするために、ノイズが酷い部分をLocal単位でぼかす羽目になった。天文写真としてはぎりぎりの線かも。
