The constellation of Corona Australis and the dark nebula area known as the Field of Nothing, as in a telescope at moderate power, there is nothing in the eyepiece. The small globular cluster NGC 6723 is at left. The field simulates a binocular field of view. This is a stack of 5 x 2-minute exposures with the 200mm lens at f/2.8 and Canon 5D MkII at ISO 1600, Tracked on the AP400 mount in Australia.
The Coathanger asterism of stars, aka Cr399, in Vulpecula, with the small open cluster NGC 6802 at left. I shot this from home on a very clear night on July 31, 2019, using the Astro-Physics Traveler and Hotech f/6 field flattener for a stack of 5 x 8-minute exposures at ISO 800 with the now 10-year-old filter-modified Canon 5D Mark II. Diffraction spikes added with Astronomy Tools actions..
