120mm f/5, 48x, Bortle 4, SQM-L 21.3
I only saw the brightest member NGC4169. At 48x still compact, at 85x roundish to slightly oval, condensed.

All four members were visible. NGC4169 is brightest member and apparent with direct vision. Appeared as oval nebula with brighter core. NGC4174 & NGC4175 appeared elongated, whereas NGC4174 is fairly compact. Both galaxies well seen with averted vision. NGC4173 held with averted vision, very thin & elongated, but quite faint and evenly bright. An awesome group of galaxies, especially when you see all members at once!

NGC4169 most easy, which can be seen with direct vision as an oval nebula with much brighter core. Smallest and second brightest regarding to high surface brightness is NGC4174: relatively small, elongated, apparent with averted vision. More difficult is NGC4175: Permanently held with averted vision as elongated nebula. Largest, but very faint NGC4173 not seen.
