The bright Cygnus Starcloud (at right) and collection of red emission nebulas in central Cygnus, including the North America Nebula (NGC 7000) at left near the bright star Deneb. The dark Northern Coalsack is to the right of the North America Nebula. The IC 1318 emission nebula complex is at centre. The star cluster NGC 6819, aka The Foxhead, is at far right. The cluster NGC 6866, aka The Kite, is to the left of 6819. At top right is the cluster NGC 6811. This is a stack of 4 x 2-minute exposures at f/2.8 with the Rokinon 85mm RF lens on the Canon EOS Ra camera at ISO 1600, and through the Kase Neutral Night broadband filter, with an additional exposure layered in taken through a Kase/Alyn Wallace StarGlow filter for the glows. Taken from the Alberta Star Party site on September 3, 2021, with the camera on the Star Adventurer Mini tracker. Stacked, aligned and blended in Photoshop. Luminosity mask adjustments applied with Lumenzia and Zone System Express v7.
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.
