Low surface brightness is no obstacle for cooled astronomical
camera, which can accumulate literally single photons for a long time.
And digital processing of stacked long exposure images can reveal
fantastic details, which can never be seen by eyes. Paolo De
Salvatore used his G2-8300 CCD camera on 10” RC telescope to
gather almost 12 hours of total exposure time of this galaxy. So, no
wonder his image shows incredible details.
