Veil Nebula complex in the constellation Cygnus, aka the Cygnus Loop or Cirrus Nebula. This is a remnant of a supernova explosion that occurred 5000 to 8000 years ago. It features a mix of red hydrogen-alpha and cyan oxygen III emission for a colourful complex of lacy filaments. The components have the catalogue numbers of NGC 6992-5 (eastern component at left) and NGC 6960 (western component at right, through the star 52 Cygni), and NGC 6974 for the middle area at top called Pickering's Triangle. Photographed from southern Alberta, Canada on 14 May 2023.
