Albert Marth discovered NGC 5192 = m 259, along with NGC 5196 and 5197, on 12 Apr 1864 and noted "vF". CGCG 017-001 = PGC 47503, the galaxy assumed to be NGC 5192 in modern catalogues, is 16 sec of RA west and 2' south of Marth's position. Perhaps coincidentally, his position is only 1' southwest (similar offset as nearby NGC 5196 and 5197) of VIII Zw 319, a merged triple system. Could this be the real NGC 5192?

400/500mm - 17.5" (4/7/89): extremely faint, small, very elongated SSW-NNE. Member of the NGC 5183 group.
