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 II USM at f/2.8
•Filter: Optolong L-eNhance (dual narrowband, Ha and OIII)
•Mount: Star Adventurer GTi
•Guiding: SVBony SV106 50mm guide scope with ZWO ASI120MM Mini
•Control: ASIAir
Acquisition:
•\~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: AI denoise
•Palette: HOO, with star reduction and desaturation on a separated star layer
