SSCygni is a variable star that was in outburst at the time of this image. I only occasionally do photometry of variable stars and the serie of 60 images (60s each) I made was unusable for good results because the star was almost saturated in the individual images. It was at magnitude 8.5 about at that time. During capture I noted some faint galaxies nearby, so I decided to make a stack of the images to show these galaxies somewhat better, they all are around magnitude 15!
