Body Of The Cigar Galaxy (シガー銀河の本体) Messier 82

What, Jet is not in the picture! ! I'm sure people will complain, but this time I wanted to take a look at the M82 without the jet.
I took this photo in December last year, but that time I shot at F/5.3. I'm curious about what the center looks like.
I chose this target as it was the First Light of the RC10T Prime Focus at the CSky Observatory.
If we emitted a jet with the Ha wavelength, which is a characteristic of this galaxy, it would interfere with the center, so although we photographed it, we excluded it from processing.
After applying Deconvo and HDR (Layer 6), a white worm-like structure became visible around the center. No Sharp processing was applied, which would create mysterious objects, and only Stretch (GHS) was used to emphasize it.
When I checked, I found that this existed in B and G, but it was almost never seen in R and Ha.
Is it in the relatively short wavelength range of visible light? A much thinner filament was seen in the JPL@NASA photo.
It can also be clearly seen that the disk part is depressed towards the center. Dark Lane is similarly drawn towards the centre.

なーんだJetが写ってないじゃん!!と文句を言われそうだが、今回はJetの無いM82を見て見たかった。
昨年12月にも撮影したが、その時はF/5.3での撮影だった。中心部がどうなってるかが気になり
今回CSky観測所でのRC10T Prime FocusのFirst Lightということで、このターゲットを選んでみた。
この銀河の特徴であるHa波長のJetを出すと中心部がそれに邪魔されてしまうので、撮影はしたがプロセッシングからは外した。
DeconvoしてHDR(Layer 6)かけた後から中心部周辺に白いミミズのような構造が見えてきた。謎の物体を創造してしまうSharp処理は一切かけておらず、Stretch(GHS)だけで強調している。
チェックしてみるとB,Gにこれが存在していて、RとHaではほとんど見られなかった。
比較的可視光の短波長あたりにあるのだろうか?JPL@NASAの写真ではもっと細いフィラメントで見られた。
又円盤部が中心部に向かって落ち込んでいるのが明確にわかる。同様にDark Laneも中心部に向かって引き込まれている。
