This image was made with a Nikon Z7 II and a Nikon 600mm f/6.3 PF lens at f/6.3. It is a stack of 101 40-second exposures at ISO 3200 for a total of 67 minutes of accumulated exposure time. Star tracking was with a Fornax Lightrack II. Images were processed from raw using RawTherapee AMaZE demosaicing and stacked using Deep Sky Stacker. Registered/calibrated intermediate files were then averaged, followed by stretching and color correction using custom Python routines. Some additional final image processing was done with Topaz DeNoise AI and Capture One.
