NGC 6811 in the constellation Cygnus is a
cluster comprised of approximately 70 member stars which are of
uniform brightness and very well detached from the background
sky. The cluster spans 15 arc-minutes in diameter or half the
apparent diameter of the full moon. Depending on the source, the
cluster lies between 2940 and 3960 light-years away
(heliocentric distance) with an intermediate age of
approximately 700 million years old and as evidenced by the
presence of some red giants and predominance of white hot stars
in this image.
