IC 1318
**Target:** Sadr Region (IC 1318, Gamma Cygni nebulosity), Crescent Nebula (NGC 6888), Cygnus
**Acquisition (July 8-9, 2026):**
57 x 235s lights, ISO 1600 (3h43m integration)
Bortle 6, waxing gibbous moon up for the later frames
25 darks, 50 flats, 50 bias
Guiding: 0.7-0.9” RMS total
**Equipment:**
Camera: Canon EOS 600D (astro-modified)
Lens: Canon EF 200mm f/2.8L II at f/3.5
Filter: Optolong L-eNhance
Mount: Sky-Watcher Star Adventurer GTi
Guiding: ZWO ASI120MM Mini + SVBony SV106 50mm
Control: ASIAir
**Processing (Siril + GraXpert + StarNet):**
Calibration, stack (Winsorized sigma, FWHM-weighted)
Background extraction, Photometric Color Calibration
GHS stretches, StarNet star separation
Starless: further GHS + saturation + GraXpert denoise
Star layer: red desaturation for clean star color, faint-star reduction
Star recombine
