The Sliced Onion Galaxy (スライス・オニオン銀河) NGC3344

I changed Gear to a long focus and waited for the galaxy season, but there were days when I could not even see the moon due to the clouds and rain every day.
It was clear sky today, so I finally got a picture of the galaxy.
It probably has this name because it resembles the cut end of a sliced onion.
I tried this Target many times and finally caught it for the first time today.
There is a dark arm in the part of the disc and I'm not sure if it's a disc or noise, but when compared with other photos, it looks like a disc rather than noise.
This galaxy is something difficult.
