The wonderful open star clusrter NGC 6124 in Scorpius amid a field of dark nebulas and on the edge of a bright star cloud with red emission nebulosity. I call this the Dark River Cluster. The small star cluster NGC 6192 is at bottom. Taken with a telephoto lens to simulate a binocular field of view. This is a stack of 4 x 2-minute exposures at f/2.8 with the 200mm telephoto lens, and filter-modified Canon 5D MkII at ISO 2500. Tracked on the AP 400 mount.
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.
NGC 6188 area in Ara, taken with 77mm Borg astrographic refractor at f/4.3 and Hutech-modified Canon 5D camera, for stack of 5 x 8 minute exposures at ISO 400, taken April 18, 2007 from Coonabarabran, NSW, Australia. Doublelobed planetary nebula NGC 6164-5 at upper right, and clusters NGC 6167 at lower centre and NGC 6134 at lower right.
