This image shows just a small part of the amazing vista that runs throughout the summer constellation Cygnus. At the upper right is the Crescent Nebula, NGC 6888, so called because of its appearance in a small telescope. A little below and to the left of the center of the image is a subtle but well-defined red circle; this is the Soap Bubble Nebula (PN G75.5+1.7). Amazingly, this planetary nebula was discovered as recently as 2007, by amateur astronomer D. Jurasevich. There is some oxygen-based nebulosity around 34 Cyg, the bright star on the left side of the image, but I have not been able to determine if this nebula has a catalogue name. Red hydrogen nebulosity is everywhere in this region of the sky.
