Or rather, the central part of the nebula. Cropping has left the chat. While processing the material, I realized what Samyang lacks compared to modern short-focus solutions: a built-in rotator. Theoretically, I could have rotated the lens in the loosened rings, but that would have 100% required refocusing afterward. Not expecting any decent results that night (high clouds, wind), I decided I couldn't be bothered and left the setup to shoot as it was. And I went off to watch for meteors!
