First light of the monochrome planetary camera ASI678MM with an H-alpha filter. Part of a future SHO imaging session. Basic processing in Siril (cropping, background gradient removal, deconvolution with PSF, automatic histogram stretch, black point balance). Without fanaticism, used GraXpert for noise removal (coefficient 0.2).
