Swan Nebula
Acquisition:
Around 4h30m worth of 180s subs looking toward Bortle 7 fully calibrated and dithered.
Equipment:
Evostar 72ED, iEXOS 100, ASI 533MC, Optolong L-Ultimate, 0.85x reducer+flattener, rotator+filter holder, SVbony 105 40mm guidescope, ASI 662MC guide camera with pale yellow no.8 and UV/IR cut filters.
Processing:
\-OSC Drizzle preprocessing and stacking in Siril;
\-Minor cropping;
\-Background extraction and denoising in GraXpert;
\-SPCC;
\-DBXtract;
\-Pixel Math (R=HII-OIII, G=OIII, B=2OIII);
\-Starnet;
\-GHS, black point shift, curve adjustments and HDR Multiscale applied iteratively to starless;
\-Histogram transformation;
\-Cosmetic correction;
\-Mild median filter;
\-GraXpert denoising;
\-Stretch star mask and desaturate stars (I don't have the chance to shoot RGB stars easily as of now);
\-Recompose;
\-Cosmic clarity sharpening;
\-Further minor GraXpert denoising.
