The rich Starcloud in Scutum the Shield framed here with a field of view similar to binoculars, and showing the prominent star cluster M11, aka the Wild Duck Cluster, at upper left. The cluster Messier 26 is at bottom right, and the small globular cluster NGC 6712 is at lower left. The tiny green planetary nebula IC 1295 is just visible at this scale to the left of NGC 6712. The area is bounded by many Barnard catalog dark nebulas. The very red star below centre is S Scuti. The large and loose open cluster at far right near the star Alpha Scuti is NGC 6664 with the dimmer Trumpler 34 to the left of it. This is a stack of 10 x 6-minute exposures with the SharpStar 61mm EDPH apo refractor, with its flattener/reducer lens for f/4.5 and with the stock Canon R6 camera at ISO 800. Guided with the MGEN3 autoguider with dithering on but no LENR or dark frames to eliminate thermal noise or edge amp glows.
Sirius (at top), the brightest star in the sky, and Canopus (above the trees), the scond brightest star in the sky, as seen from southern New Mexico. From a latitude of +33° Canopus just clears the tops of the trees. This is a stack of 2 x 2 minute exposures with the 35mm lens at f/2.8 and Canon 5D MkII at ISO 1600.
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.
