NGC 6914 is a complex of emission and reflection
clouds nearby to the IC 1318 region. The reflection clouds are
catalogued separately as NGC 6914A (vdB131) and NGC 6914B (vdB
32), south and north respectively. The illuminating stars of the
nebula belong to the Cygnus OB2 association. This massive grouping
of young stars is arguably the most massive and extensive stellar
association in the Milky Way. It contains about 2600 OB type spread
across 200 light years of space. Its total gaseous mass is estimated
to be several hundred thousand solar masses. The stars are mostly
obscured by the extensive dust clouds of the Milky Way in that
area known as the great rift.
