A photo of the "Wild Duck Cluster", in Scutum, photographed from St. John's on July 15, 2010 by Chris Stevenson. M11 "Wild Duck Cluster in Scutum", 3x30s exposures with 11-inch Celestron CPC-1100 on wedge in SkyShed POD, modified Canon 350D, all sums of 30s exposures, roughly half usable, using Registax4. All had the same 30s dark subtracted from them, and (unfortunately), no flat field division. Ambient temperature 12-14C. Curves in linux' The Gimp. Click image for full original photo.

A photo of "Open Cluster", in Cygnus, photographed from St. John's on July 15, 2010, by Chris Stevenson. M29 Open Cluster in Cygnus (3x30s exposures with 11-inch Celestron CPC-1100 on wedge in SkyShed POD, modified Canon 350D, all sums of 30s exposures, roughly half usable, using Registax4. All had the same 30s dark subtracted from them, and (unfortunately), no flat field division. Ambient temperature 12-14C. Curves in linux' The Gimp. The relative size of the faint and bright stars here indicates, perhaps, the relatively mediocre 'seeing') Click image for full original photo.
