The bright star just to the right and lower than center is 56 Cygni, a double star the brightest component of which is magnitude 5.07 and type A6V. 56 Cygni is about 134 light years away. The bright star at upper right is 57 Cygni, 530 light years away and type B5V. The nebula itself is far in the background at 1800 ±200 light years. Of course, the nebula has several layers. The darker parts superimposed on the brighter emission nebulae are closer. I've always suspected that the rounded ridge on the right with the Loch Ness Monster rising out of it is most near after the dark parts.
