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.

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。
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。
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。
