An observation in February 2018 from dark (and cold! -10C) northern Germany. 14" SCT @ 168x / 29':
All four galaxies are visible, a beautiful group. A - NGC3190 is elongated NW-SE and is suddenly brighter in a core that is slightly elongated in the same direction with a bright nucleus that is visible without AV. Has somewhat irregular structure and is flattened on the south side on a line from SE to NW; that will be due to the dark lane in the galaxy but the lane can not be discerned. To the NW is D - NGC3187, to the NE is B - NGC3193, 1/3 FoV to the SSW is C - NGC3185. B - NGC3193 is a round glow, suddenly brighter in a round core with a bright nucleus that is visible without AV. To the NNW is a mag. 9 star (SAO81279). C - NGC3185 is a NW-SE elongated glow, quite suddenly brighter in a core that is slightly elongated in the same direction, with AV the extremely faint nucleus is at the limit of visibility. To the SW is a mag. 15 star. D - NGC3187 is an extremely faint, NE-SW elongated glow, even in brightness, no detail visible and difficult to observe without AV.
