An extremely faint object. At 300 seconds, it's completely invisible; at 600 seconds, you can't even guess the outlines; only at 900 seconds do the contours just begin to show. The integration is low, there's a lot of noise, and the stars aren't great, but I still like it. I spent a very long time processing it, with many, many attempts, and I'll keep this version. I will definitely re-shoot it with proper integration, but this version is precious in its own way—I refined my processing here and applied a lot of new techniques I've learned recently.
