Photo description / processing

Shot at the end of summer - beginning of autumn 2025. 10 nights because it's the south, low on the horizon and constant clouds. My own palette based on classic SHO, calibration, stacking and star removal in PixInsight, all post-processing in Photoshop, without paid AI plugins. Denoise and background in GraXpert.
