While it can be seen in the colour version, as an outer gossamer glow, slightly stretching the luminance data and viewing in B&W
better reveals the very faint outer halo surrounding these two galaxies. Doing this shows this outer halo is surprisingly extensive,
extending out quite some way around both galaxies and in all directions. There are billowing extensions at the end of each
"antennae" and the long antenna now appears almost like two star streams, side by side, running parallel to each other!
