M15 with AstroDMx Capture for the Raspberry Pi, an SVBONY SV305 camera and a 130mm F/5 Newtonian

 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.

Nicola's AstroDMx Capture for the Raspberry Pi running on a Raspberry Pi 4B with the 32 bit Raspberry Pi OS, was used to capture 40 x 30s exposures of the globular cluster M15 as 16 bit Tiff files with matching dark-frames.

The best 36 frames were aligned and stacked in Deep Sky Stacker. The resulting image was post processed in the Gimp 2.10, Affinity photo, and Neat image.
