Images acquired using CCD-Commander and TheSkyX
PixInsight workflow:
RGB processing: GradientCorrection, SPCC, BlurX, then MAS followed by NoiseX then HistogramTransformation,
H-Alpha and OIII processing: GradientCorrection, BlurX then StarX then HistogramTransformation and Curves on the starless images.
Save all as TIFF and then moved to Photoshop:
OIII and Ha were layered over the RGB using Lighten blend mode and the Ha was dropped only on the Red channel and OIII only on the Green & Blue channels. Selective Colour and Vibrance layers were added for punch.
