M31 (Andromeda)

M31, the Andromeda Galaxy. It was periodically photographed from 2023 onwards, every summer when the sky allowed. Calibration, stacking - PixInsight, processing in Photoshop and GraXpert, without neural network deconvolution. Without aggression and boosting saturation, the goal was specifically to preserve the dust at the edges. Hydrogen is already appearing in the background at the top, so it seems like there's a reddish gradient. Plans include collecting another 15-20 hours of oxygen data as it has only just started to appear; I specifically didn't suppress it during processing. And another 10 hours or so of hydrogen data. Hydrogen is mixed into the red channel, oxygen into the blue and green channels evenly.
