A mosaic of the region around the centre of the Milky Way in Sagittarius and Scorpius. The field takes in the Milky Way from the Cat's Paw Nebula at bottom edge to the Eagle Nebula at top left. In between from top to bottom are the Swan Nebula (M17), the Small Sagittarius Starcloud (M24), the Trifid and Lagoon Nebulas (M20 and M8) and the open clusters M6 and M7. The prominent dark nebula at right is the large Pipe Nebula (B78) with the small Snake Nebula (B72) above it. The whole complex is visible to the naked eye as the Dark Horse. This is a mosaic of 6 panels, each a stack of 5 x 3 minute exposures with the 135mm lens at f/2.8, and with the filter-modified Canon 5D Mark II at ISO 1600 tracking the sky on the iOptron SkyTracker, with no guidind. Images were stacked and stitched in Photoshop CC. Taken from the Four Bar Cottages near Portal Arizona, May 4/5, 2014.
A panaoramic mosaic of the southern Milky Way region from the Coal Sack dark nebula and Alpha Cruxis, (aka Acrux) at left, to IC 2944/8, the Running Chicken Nebula, at right, with the star cluster, NGC 3766, above. The cluster IC 2714 is at the lower right corner. The star cluster NGC 4609 is left of Acrux, in the Coal Sack. This is a 3-panel mosaic, each panel a 4 x 6-minute exposure with the Borg 77mm f/4 astrograph and filter-modified Canon 5D MkII at ISO 1600. Stacking and stitching in Photoshop CC 2015. Taken from Tibuc Cottage, Australia, April 11, 2016.
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.
