Sadr, the central star of the Northern Cross, is surrounded by extensive regions of emission nebulosity. One such region is IC 1318, also known as the Bufferfly Nebula. The dark lane separating the two "wings" is a dark nebula known as LDN 889. The bright cluster of stars near the upper-left of the image is NGC 6910. 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 at the 2010 Okie-Tex Star Party (in the far western panhandle of Oklahoma). Clicking the above image will bring up a higher resolution image. |
