Messier 25, a bright star cluster in Sagittarius, shot from home on a very clear night, August 4, 2019, with the object low in the south. This is a stack of 6 x 8-minute exposures with the Astro-Physics Traveler 105mm apo refractor at f/6 and Canon 6D MkII at ISO 800. I used the AP 6x7 field flattener here. LENR darks subtracted in camera. Diffraction spikes added for artistic effect with Astronomy Tools actions.
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.
