Photo description / processing

The Garlic Nebula, also known as LBN 576 (Abell 85) Mount: MT-90 OTA: TS-Photon 8" f/4 Coma Corrector: Sharpstar 0.95x Camera: ZWO ASI 533C Pro Filter: Optolong L-eXtreme Guide Scope: Svbony 60/240 Guide Camera: T7 Astro Total Integration: 1.92 hours Single Frame Exposure: 300 seconds Bin: 1x1, Sensor Temperature: -5°C ISO/Gain: 100 Full calibration with 30 frames each (darks, biases, flats) Processing: DSS, FITStacker, PixInsight, Ps. Sky Brightness: Bortle Orange Zone Date: October 27, 2022 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.
