AstroDMx Capture for macOS, a Bresser Messier-AR-102-xs f/4.5 ED refractor, an Atik 314L mono CCD camera with a H-alpha narrowband filter. The scope/camera combination were mounted on a Celestron AVX GOTO mount.
AstroDMx Capture for macOS was running on a MacBook Air computer.
40 x 60s exposures were captured of M16 as 16 bit Tiffs with matching dark-frames.
The images were stacked and dark-frame corrected in Deep Sky Stacker and post processed in the Gimp 2.10 and Affinity Photo.
