The small constellation of Sagitta the arrow in the Milky Way, with the cluster M71 left of centre. 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.
The summer constellations of Sagittarius and Scorpius skimming low across the south from my latitude of 51° N, above the trees from my backyard site in rural Alberta. In this version I added in labels for the major stars, constellations and the deep-sky objects that are easily visible in binoculars, if not to the naked eye. I also included a binocular field of view circle for scale. The M objects are from the Messier catalogue. Jupiter is the bright object right of centre; Saturn is left of centre. Altair is at upper left. A number of deep-sky objects show up, particularly the Messier nebulas and star clusters, as well as the Scutum Starcloud left of centre, and above it several large binocular open star clusters. The constellation of Ophiuchus is at right of centre occupying most of the frame. Aquila is at far left along the Milky Way. This is a stack of 4 x 1-minute tracked exposures with the Nikon D750 at ISO 1600 and Sigma 24mm lens at f/2.2, plus one of those exposures blended in for the ground to minimize its blurring. Another exposure taken through the Kenko Softon A filter was blended in to add the star glows, though light cloud this night added some glows naturally.
Saturn, the bright object at upper right, in the head of Scorpius in March 2015. Antares is the bright yellow star below, just right of centre. The centre of the Milky Way is at left, with the bright star clouds of Sagittarius above the star clusters Messiers 6 and 7. The reddish Lagoon Nebula, M8, is above centre at left. The “Dark Horse” made of dark dust lanes is left of centre. This is a stack of 4 x 2 minute exposures in the dawn twilight, March 26, 2015, with the 50mm lens at f/2.8 and Canon 6D at ISO 800, tracked on the Star Adventurer.
