The Box. Very nice group of NGC-galaxies. NGC 4173 (12.7 mag) and NGC 4175 (13.4 mag) are two highly elongated galaxies on the very same line. NGC 4173 is larger and harder, it's visible with averted vision. NGC 4169 (12.2 mag) and NGC 4174 (13.5 mag) are smaller elliptical galaxies on the south-side.
