The "Cygnus Bubble" nebula may actually be a cylinder that is being seen from one of its ends. This image was taken with the Kitt Peak Mayall 4-metre telescope in Arizona (Image: Travis A. Rector/U of Alaska Anchorage/Heidi Schweiker/NOAO)
Low lit photography, ISO 800 and f/1.8 gives better exposure, the only source of light was emergency lamp (expereincing dark days, due to lack of rain)
