This is the open cluster NGC 6124 in Scorpius, a beautiful object and field for binoculars. This field is about 10° by 6° wide, so approximating the field of typical binoculars. Note the many dark lanes of dusty nebulosity that winds through this field. This is a stack of 6 x 2 minute exposures at f/2.8 and ISO 1250 with the 135mm Canon telephoto lens on the Canon 7D, and was taken May 1, 2011 from Atacama Lodge in central Chile.
