The Seagull nebula is part of the Canis Majoris OB1 association and Canis Majoris R1 reflection nebula complex at a distance of 3750 light-years (1150 parsecs).
Most of the nebulosity visible on the bottom of this image is part of the Seagull's Wings (catalogued as IC 2177 or Sh2-296).
The Seagull's Head (catalogued as NGC 2327 or Sh2-292 or even Gum1), located just on the border between the constellations Monoceros (the Unicorn) and Canis Majoris, is both an HII region and reflection nebula (catalogued as vdB 93) and is ionized by the B0 subgiant HD 53367, a young 20 solar mass star with a 5 solar mass companion in a highly elliptical orbit.
