8. There are some 430 stars within L935.
9. The visual magnitude of the nebula is 8.0.
10. The Pelican Nebula is located some 1,800 light years from Earth.
11. The nebula lies close to the star Deneb, the brightest star in the constellation Cygnus.

13. Both, the Pelican Nebula and North American nebula are part of a massive Hydrogen-II emission region which is located in Cygnus and is designated as W80.
14. The two bright stars visible in most images of the nebula are 56 Cygni (lower right) and 57 Cygni (lower left). These two stars are located in front of the nebula.
