Description:
I belive this duo of galaxies is probably the most remarkable member of the enormous Coma/Virgo supercluster of galaxies. The FoV is dominated by the two interacting galaxies also known as The Siamese Twins or Butterfly Galaxy. They are not really bright, and with no sign of an outstanding central bulge. The third galaxy of the FoV, NGC 4564 has a similar brightness, but is much smaller than the twins.
SQM reading: 21.38 m/arcsec2, 7°C. The upper atmosphere is very humid with Venus having a clearly visible halo.
