Messier 26 open star cluster, at right, a bright binocular/telescopic star cluster, along with the fainter and small globular star cluster NGC 6712 at upper left, which itself is paired with the faint planetary nebula IC 1295, the greenish spot left of NGC 6712. All are in the constellation of Scutum, embedded in the rich Scutum Starcloud. The bright red star at top is S Scuti. This is a stack of 8 x 6 minute exposures at f/4.4 with the Canon 6D at ISO 800 and TMB 92mm Apo refractor with the Borg 0.85x flattener/reducer. Taken from the winter home near Silver City, New Mexico.
M27 with 130mm Astro-Physics apo at f/6 with no field flattener (slight camera tilt results in more coma at left of frame), for stack of 6 c 8 minute exposures at ISO 800 with Canon 7D (stock camera, not modified). Auto-guided with SG4. Worked perfectly.
Messier 27, the Dumbbell Nebula in Vulpecula, a popular deep-sky object and one of the finest examples of a planetary nebula in the sky, a nebula blown off in shells by the solar winds and eruptive events at the end of the life of a Sun-like star. This is a stack of 9 x 6-minute exposures with the Sky-Watcher Quattro 8-inch astrographic Newtonian reflector, at f/4 with the coma corrector. The camera was the filter-modified Canon 5D MkII at ISO 800. Shot from home, Oct 12-13, 2015.
