Messier 23, 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 5 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.
