      M20 Widefield HSO & LRGB

      M20 Widefield HSO & LRGB

      This wallpaper is a combination of two datasets from TL3, both titled M20 widefield—one in LRGB and the other in HSO. The stars are taken from an LRGB starless version and combined with an averaged starless image using both LRGB and HSO data. The processing was done in AstroPixelProcessor and PixInsight, with the final blend using an avg(x,y) PixelMath formula, inspired by the workflow shown in Masters of PixInsight: Photons to Photos #29.

      My processing of the M20 widefield image was inspired by a recently released photo from the Vera Rubin Observatory in Chile.
