A deeper image of Cygnus stretches from Deneb at upper left to Albireo at
lower right. Sadr is just above center, Delta to upper right, Gienah to
lower left. The North America Nebula is barely visible to the left of
Deneb, while the Cygnus Loop can be just seen down and to the left
of Gienah. The hypergiant P Cygni is smack in the middle; faint
Cygnus X-1 (supergiant plus black hole) is down and to the right of it,
and is better in the more detailed image.
