Sagitta with M71 cluster, with 135mm Canon L-lens at f/2.8 and Canon 20Da camera at ISO 800 for stack of 4 x 3 minute exposures. Taken Sept. 8, 2007. Simulates binocular field. Added glow layer to accentuate stars.
The small constellation of Sagitta the arrow in the northern summer sky. At left of centre is the Messier 71 star cluster. At upper left is the M27 Dumbbell Nebula. The field is about equal to a binocular view, as it was shot with a 135mm telephoto on the Canon 60Da. This is a stack of 4 x 80 second exposures at f/2.2 and ISO 1600, unguided on the Sky-Watcher Star Adventurer tracking mount. Two additional exposures with the Kenko Softon filter blended in to provide the fuzzy star glows. Taken from home, August 18, 2014.
A telephoto closeup of a region of the Milky Way containing an odd assortment of targets: the small constellation of Sagitta the Arrow (at bottom) with the small cluster M71, the green Dumbbell Nebula, M27, in Vulpecula the Fox (at upper left), and the asterism known as the Coathanger (at right), also known as Brocchi’s Cluster. This is a stack of 9 exposures, each 1 minute at f/2 with the 135mm lens and Canon 6D MkII (not filter modified) at ISO 1600, on the SiFo MSM low-cost tracker, taken as part of testing. Taken from home on a partly cloudy night August 21, 2019.
