The field of NGC 5457 (M 101) or Pinwheel galaxy. North is up and east is to the left. The zoomed-in squares show the LSB galaxies in the image. The red squares are five dwarf galaxies reported by the Dragonfly project (DF-number), which are all confirmed. The green square is the one newly discovered in our image (NGC 5457-DGSAT-1). Two of the Dragonfly LSB galaxies, namely the DF-2 and DF-5, are outside the field of our image.
