The Perseus Double Cluster consists of two open clusters that are seperated by only 30 arc-seconds (about the width of the moon) visually, and are only a few hundred light years apart. Both clusters are naked eye objects just a short distance from the 'W' of Cassiopeia. Both are approximately 7000 light years from Earth The star clusters are an ideal target for binoculars or a low power telescope. Both red and blue stars are visible. This image was taken in November, 2006 at the ASLC's 'Upham' dark sky site. Skies were completely transparent; seeing was moderate. Clicking on the image brings up a larger, more detailed image. |
