Cygnus region at 50mm F2.8, captured crossing the zenith at near 1600m altitude on Navarredonda de Gredos, Ávila (Spain). 

"First" light for a second-handed astro-modified Canon EOS 6D. This camera has some issues, the filter is scratched and probably not parallel to the sensor, as the non-flat-corrected images show some interference banding.
