The pair of large and loose star clusters on the Serpens-Ophiuchus border known as the S-O Double Cluster. IC 4756 is at left; NGC 6633 is at right. Both are fine targets for binoculars. The 7.5 x 5° field is close to a binocular field of view. This is a stack of 10 x 6-minute exposures with the SharpStar 61mm apo refractor at f/4.5 and with the Canon R6 at ISO 800. Taken from home Oct 3, 2021. Diffraction spikes added with Astronomy Tools actions.
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 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.
