The small constellations of Sagitta (pointed up at centre) and Vulpecula (upper right) between Albireo (far right) and Altair (far left) in the northern summer sky. The Coathanger cluster, Cr399, is at bottom centre. The Dumbbell Nebula, M27, is at top centre. The M71 globular cluster in Sagitta is at centre, below the arrowhead star in Sagitta. This is a stack of 2 x 2-minute exposures with the 85mm Rokinon lens at f/2 and Canon 5D MkII at ISO 1600, with an additional exposure through the Kenko Softon filter layered in to add the star glows. Taken from Quailway Cottage in Arizona, with the Star Adventurer Mini 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. 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.
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.
