The veil nebula
first light with a Canon EF 200mm f/2.8L
Object: The Veil Nebula / Cygnus Loop, a supernova remnant in Cygnus roughly 2,400 light years away
Gear:
• Camera: Astro-modified Canon EOS 600D (T3i)
• Lens: Canon EF 200mm f/2.8L I| USM at f/2.8
• Filter: Optolong L-eNhance (dual narrowband, Ha and OIlI)
• Mount: Star Adventurer GTi
• Guiding: SVBony SV106 50mm guide scope with
ZWO ASI120MM Mini
• Control: ASIAir
Acquisition:
• 1\~42 x 200s lights, roughly 2.3 hours total integration
• Calibration: 17 darks, 50 flats, 50 bias
• Bortle 6 backyard
• Night of June 17/18, 2026 Processing:
• Siril 1.4.2: stacking, background extraction, background neutralization, channel extraction, GHS stretching, HOO recombination, star removal
• GraXpert 3.0.2: Al denoise
• Palette: HOO, with star reduction and desaturation on a separated star layer
