The Coathanger star cluster and asterism in the Milky Way in southern Cygnus, aka Collinder 399 or Brocchi’s Cluster. The field is similar to what a pair of large binoculars would show. I shot this from home Nov. 25, 2019. This is a stack of 6 x 2-minute unguided exposures with the 200mm Canon telephoto at f/2.8 and stock Canon 6D MkII at ISO 1600. An additional exposure taken through the Kenko Softon A filter adds the star glows. All were with the camera on the Fornax LighTrack II tracker.
Taken with 4-inch apo refractor at f/4.5 with Canon 20Da camera at IS0800 for 5 minutes. Stack of two exposures. One layer median filtered and gaussian blurred to enhance glows around stars.
