About this image

SS Cyg is dead centre in this image (which I didn't want to mar with red lines). The system is in quiescence at the moment - at mag 12, which is the typical brightness for this state. You can also just make out in this image a chain of galaxies below the brightest star in the field (which is amazing as Cygnus is a Milky Way constellation).
