A Skywatcher Explorer 130 PDS 130mm, f/5 Newtonian was mounted on a Celestron AVX GOTO mount. An SVBONY SV305 camera was placed at the Newtonian focus.
A Raspberry Pi 4B was running 64 bit Ubuntu Mate for the Pi. AstroDMx Capture for the Raspberry Pi was used to capture 30 x 60s exposures of M27, the Dumbbell nebula with matching dark-frames
The best 26 exposures were aligned and stacked with Deep Sky Stacker. The final image was post-processed in the Gimp 2.10, Affinity Photo, Neat Image and ACDSee.
