The Sombrero Galaxy. Like a Saucer (ソーサーのようなソンブレロ銀河) Messier 104
I really wanted to photograph the back arm of this galaxy myself, so I lowered the brightness of the halo as much as possible.
It looked like a soucer.
However, I can't see it clearly, and the resolution is low to begin with, so I can't separate the details of the Dark Lane in the foreground.
M104 taken with IMX294-C using the same RC10 F/8 Prime Focus last year was able to show the Dark Lane's detail more than this photo.
After all, I have to remove Redeucer and make it work with PrIme Focus.

When re-sampling is done to 300%, the stars become enlarged and look unsightly.
どうしても、この銀河のコアの反対側のアームを見たくて、コアとハローの輝度を極力落としたら
Tea cupのお皿っぽくなった。
RC10 F/5.3では構造がクリアには見れていないし、そもそも解像度が低くて手前のDark Laneの詳細も分離が弱い。
RC10のF/８のPrime Focusではコアの反対側もみれて円盤の構造も良くなってきた。でも暗黒帯がダメだな。
RC10のF/8とF/5.3を合わせてIntegration。暗黒帯がマシなってきた。
