The Burbidge Chain Galaxy (くじら座の銀河)NGC247

It looks like the same cluster of galaxies as the Sculptor galaxy, but it is an extremely pale galaxy compared to Sculptor, and I had a bad feeling when I started shooting.
At this south position, it feels like rushing into the sea of light pollution from the Backyard. I shot for several hours in several days, but quite a lot of Frames went to the trash can, and the effective Frame was about three and a half hours.
Even for three and a half hours, it overlaps with light pollution, and the result is this lightness.
I thought I'd add Ha, but I'm boring to add Ha to this lightness, so I'll stop.
It is Share because it is a pale memorial galaxy.
