P Cygni

(sig -nÿ, -nee) A massive luminous blue variable about 2000 parsecs away in the constellation Cygnus. It has undergone random outbursts: in both 1600 and 1653 it brightened considerably then faded, but since 1700 its brightness has very gradually increased. It is also an ultraviolet source that is gradually cooling, the UV brightness decreasing as the visual brightness increases. See also P Cygni stars.

Look for it one-third of the way from Gamma ([gamma]) to Eta ([eta]) Cygni or 1.2[degrees] west-northwest of 34 Cygni. There you'll find a pair of 7th-magnitude stars embedded in the nebula.
Let's return to 34 Cygni and then slide 28' south-southwest to the open cluster IC 4996.
IC 4996 is thought to form a double cluster with the P Cygni Cluster, which has the bright star 34 Cygni at its eastern edge.
