M13 is large, bright globular cluster found in the Hercules constellation.
This image was taken using an STF-8300M camera on a CFF132 refractor. It was taken from my back yard in the city and is a little over two hours of integration time.
There was minimal processing done to this image. The short integration time shows as background noise and slightly blocky stars. The color is balanced better than most of the other versions of M13 on this site. But the saturation level is low so there is not much color and it mostly comes out as white.
