Description

Processed using a minimalist approach in PixInsight: Photometric colour calibration, SCNR, MLTnoise (not much), Histogram stretch (not as much as STF), further stretch with luminosity mask applied to mask larger stars, then stretched and saturation increased to my liking with Curves. ColorProfile adjusted for web.
