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 portrait of the northern autumn constellation of Cepheus the King. The large red nebula at the bottom (to the south) is IC 1396. Mu Cephei is the red star, aka the Garnet Star, on its edge. This is with the filter-modified Canon 5D MkII camera at ISO 1600 and Sigma 50mm lens at f/2.8 for a stack of 13 x 60- and 90-second exposures with the Star Adventurer tracker (median combined to help eliminate thin clouds drifting through), plus an exposure through the Kenko Softon A filter layered in for the star glows.
This is a portrait of the southern region of Cepheus the King that takes in the red emission nebulas in the constellation. The area is also laced with dark lanes of dust. The main nebula is IC 1396, aka the Elephant Trunk Nebula, at bottom. Above and to the right is the arc of Sharpless 2-129. At lower left is NGC 7380 near the edge and Sharpless 2-132, the Lion Nebula, at bottom left. Sharpless 2-140 is at upper left. Unfortunately, the Cave Nebula Sh 2-155 is just cut off at upper left. The stars above IC 1396 are part of the Cepheus OB2 stellar association. The very orange star at centre on the edge of IC 1396 is Herschel's Garnet Star, aka Mu Cephei. The double star and variable star Delta Cephei is at lower left. This is a stack of 17 x 1.5-minute exposures with the Canon EF-L 135mm lens at f/2.8, on the red-sensitive Canon Ra at ISO 1600, all on the Star Adventurer Mini tracker. The lens was also equipped with a Haida Clear Night light pollution reduction filter. Taken from home on a very clear night in late August. An application of a Pro Contrast filter from the Color EFX plug-in from the Nik Collection 5 helped snap up contrast and bring out the nebulosity, as did using curves with luminosity masks generated by the Lumenzia extension panel. All stacking, aligning and processsing in Photoshop.
