Photo description / processing

IC1848: The Soul Nebula — August 30, 2025. Player One Ares-C Pro, AM5N, RASA 8". Filter: Antlia Ha-Oiii for fast systems. Frames: 157, F: 400mm, F/2.2. Exposure: 120 sec. Total: 18840 sec = 5.2 hrs. Gain: 100. Flats, darks, biases. I also made two other versions, but they turned out more disappointing. This version benefited from a second pass through GraXpert Denoise. The start of the imaging season. I need to capture at least the simplest target, since it's not yet available in any decent quality. This catalog contains darks, flats, and biases. Processing: In PixInsight (a yellower version) using the revolutionary MAS: auto DBE, blurX, noiseX, MANS, starX, LHE, curves+histo, white balance adjustment; In Siril (a whiter version), GraXpert, starnet, GraXpert, recomposition. The original was not preserved; only a recompressed version from Google Photos remains.
