Twenty Four Hours at the Cygnus Wall

[AMcD]

The final version of my image of the Cygnus Wall in NGC7000 comprising 24.6hrs of 300 sec subframes taken using a QHY8 OSC with an Optolong L-Extreme filter on a TS152 achromatic refractor mounted on a Losmandy G11.  Integrations acquired using SGPro guided with PHD2 from Bortle 5 skies.  Stacked with flat frames in DSS (the QHY8 does not ordinarily need darks).  Processing in PS.  The 32 bit DSS tiff file was cropped, rotated, a medium/medium Gradient Exterminator applied, adjusted in levels and converted to a 16 bit tiff file in 'Gamma and Exposure'.   Three 'Curves' stretches were then applied to the 16 bit tiff file, followed each time by adjustment of the black point in 'Levels'.  Noel Carboni's Astronomy Actions for PS was then used ('Enhance DSO and Reduce Stars' / 'Local Contrast Enhancement' / 'Reduce Stars / 'Fade Sharpen to Mostly Lighten').  'Select and Mask' was used to sharpen selected edges.  Final tweaks in PS with 'Colour Balance'. 'Hue and Saturation' and 'Brightness and Contrast'.  Tiff and PNG versions below:
