Lagoon Nebula
This is a reprocess of the image I took a couple of weeks ago. I realized that I took my bias and dark frames with a different white balance and that was messing with my data resulting in tons of nasty gradients.
Acquisition:
Around 7h30m worth of 60s subs in Bortle 6/7 fully calibrated and dithered.
Equipment:
Evostar 72ED, iEXOS 100, ASI 533MC, Baader UV/IR cut, 0.85x reducer+flattener, SVBony 40/160 guidescope, ASI 662MC guide camera with no.8 pale yellow and UV/IR cut filters.
Processing:
Stacked in Siril. Apply SPCC. Open GraXpert, crop and background extraction. Open Siril, deconvolution. Open GraXpert, denoise. Open Siril, generate starless and starmask. Black point shift and GHS to starless, histogram transformation to tame residual color cast, curve adjustments to accentuate contrast between features plus SCNR. Mild VST denoise and median filter. À trous wavelet transform to higher layers. Open GraXpert, denoise. Open Siril, Asinh stretch and saturation boost to stars. Recombine starless and starmask.
