The region around the bright star Sadr (gamma Cygni) is rich with nebulosity (much of which is IC 1318), and also contains several open star clusters such as M29 (the cooling tower cluster). Among the brighter emission nebula regions present is the Crescent Nebula (NGC 6888) and several members of the Lynd's Bright Nebula catalog. There's even a small dark nebula (B334) located directly above Sadr. Sadr shines at magnitude 2.2, and is about 1550 light-years from Earth. The name is Arabic for "The Hen's Chest". This object was imaged from ASLC's dark sky site near 'Upham' (wherever that is), New Mexico Clicking the above image will bring up a higher resolution image and a larger field of view. |
