Ring Nebula (リング星雲) Messier 57

As I have been shooting galaxies, clusters, and nebulae, I suddenly missed the planetary nebula.
It seemed that I could shoot for about an hour until twilight, so I aimed the telescope at the M57 for the first time in a year.
Similar in shape to the Helix Nebula, but smaller in size.
Since the shooting time is short, I thought it would be okay if the contrast between the blue in the center and the red in the periphery was clear, but it was Lucky who also caught the pattern on the wall in the periphery. This part was captured by the Duo Band.
