Description

M1 in Ha, 8 hours exposure.

For this image, I was experimenting with the tone mapping workflow, ie remove the stars from the image, create two images (stars and starless), process them separately and then add back the stars to the starless image.

Workflow in PI:

-Calibration-Integration

-Mure Denoise

-Dynamic Crop

-Dynamic Background Extraction

-Deconvolution

-Stretch to Non Linear (Revision B)

-Split image in Stars and Starless with Starnet++ (Revision C)

-Denoise background with MultiscaleLinearTrasformation and TGVDenoise

-Sharpen nebulosity with HDRM and LocalHistogramEquilisation

-Add the stars back with Pixelmath

-Final Sharpening with MultiscaleLinearTrasformation (Revision A)
