I have taken faint nebulosities distributed around about 4 degrees west region of the Great Orion Nebula (M42).
A dimmed H-alpha region of Sh2-278 is a part of hydrogen gas forming the Orion Association, has an apparent size of 40×15 arc minutes. And you can detect that extraordinary faint bluish gas has been distributed around Sh2-278.
