Sirius and Canopus, the two brightest stars in the night sky, together in the Arizona winter sky, with Canopus just clearing the horizon low in the south. Sirius is in Canis Major, while Canopus is in Carina, formerly part of Argo Navis. I shot this December 7, 2015 from the Quailway Cottage near Portal, Arizona, at a latitude of +32° N. Airglow adds the green bands. The open cluster M41 is visible just below Sirius. Several other star clusters in Puppis just show up as well below Canis Major. This is a stack of 5 x 2-minute exposures at f/2.8 with the 35mm lens and Canon 5D MkII at ISO 2500, on the iOptron Sky-Tracker.
Sirius, the brightest star in the night sky. Below is the star cluster M41. Shot with the 200mm lens to simulate a binocular field of view. A stack of 2 x 2-minute exposures at f/2.8 and Canon 5D MkII at ISO 2000,
This is an impressive area of sky rich in bright and dark nebulas and open star clusters in Sagittarius and Serpens. This is closeup of the Small Sagittarius Starcloud, aka Messier 24, at bottom right, with the field extending north to include the nebulas M17, the Swan Nebula, and M16 at top right, the Eagle Nebula. Between M17 and M24 is the small star cluster M18. Patches of red and blue nebulosity at bottom right below M24 are IC 1283 and the blue reflection nebulas NGC 6589 and 6590. The prominent dark nebula at the right (west) edge of the Starcloud is Barnard 92 with its lone star embedded in it, with smaller B93 above it. At the left are the star clusters M25 (bottom) and NGC 6645, with the large dark nebula B312 above. This is a stack of 3 x 6-minute exposures with the William Optics RedCat 51mm astrograph at f/5 and the Canon EOS Ra at ISO 800 with LENR on as it was the warmest night of the summer, August 17, 2020. Aligned, stacked and mean combined in Photoshop. Autoguided with the ZWO ASIAir and ASI120MM guide camera with the RedCat on the Astro-Physics Mach1 mount. No filters employed here. Clouds thwarted more exposures.
