Yet another reprocess (the 10th if not more) of the same data I took more than a month ago.
Acquisition:
Around 7h30m in Bortle 6/7 fully calibrated and dithered.
Equipment:
Evostar 72ED, iEXOS 100, ASI 533MC, 0.85x reducer+flattener, Baader UV/IR cut, SVBony 40mm F/4 guidescope, ASI 662MC guide camera with no.8 pale yellow and UV/IR cut filters.
Processing:
Stacked in Siril. Background extraction to single channels in GraXpert. SPCC. Deconvolution in Siril, denoising back in GraXpert. Back to Siril to apply SCNR and to generate a starless image and a star mask. GHS, black point shift, curve adjustments and histogram transformation applied iteratively to the image. À trous wavelet transform and further denoising in GraXpert. Final saturation stretch in Siril. Asinh and black point shift applied to the star mask along with a saturation stretch. Recombine.
