Lagoon Nebula
Acquisition: around 8h20m worth of 60s subs fully calibrated in Bortle 6/7, dithered every 10 frames.
Equipment: Evostar 72ED, iEXOS 100, ASI 533MC, Baader UV/IR cut, 0.85x reducer+flattener, SVBony 40/160 guidescope, ASI 662MC with UV/IR cut and no.8 pale yellow filter.
Processing: Stacked in Siril. First cropping and SPCC in Siril. Background extraction in GraXpert. I used the AI model because of very nasty gradients, I couldn't get it to work with RBF; this object doesn't rise much at my latitude. Open Siril again, further SPCC, deconvolution, noise reduction, mild median filter, generate starless and starmask. Black point shift and GHS applied iteratively to starless, histogram transformation, mild curve adjustments, SCNR, mild à trous wavelet transform sharpening, further mild noise reduction. Asinh stretch and saturation boost to starmask.
