S-O Double Cluster consisting of: IC4756 in Serpens (at left) and NGC6633 in Ophiuchus (right), two good binocular objects. Thru Vixen 108DD astrograph at f/5 with Pentax 67 body and Fujichrome 400F slide film. 540mm focal length with about 7.5° wide field. Exposure about 20 minutes long taken in moonlight from rising waning Moon. Thus the blue sky which has been emphasized rather than neutralized. Taken July 2003 from home.
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.
