M13 in a Moonlit sky with a DFK, a Bresser Messier AR 102xs f/4.5 refractor and a little Python code

I have been writing Python code using OpenCV3 to capture images and AVIs from a DFK 21AU04.AS camera.
A Bresser Messier AR 102xs f/4.5 refractor fitted with a Skywatcher motor focuser was placed on an HEQ5 GOTO mount. A DFK 21AU04.AS camera was placed at the prime focus and thirty 15s exposures of M13 were captured as Tiff files in a bright moonlit sky, with 10 matching dark frames. The best 27 frames were stacked in Autostakkert!3 and the resulting image was post processed in the Gimp 2.10.
