John Herschel discovered NGC 1375 = h2558 in the Fornax Cluster and described "B, S, lE, pmbM; the 3d of 3 [with NGC 1373 and 137] of the same RA as the second." His RA is 7 sec too large, but Julius Schmidt's position (measured on 19 Jan 1865 with the 6.2" refractor at the Athens Observatory and listed as nebula "c") is accurate in RA.

300/350mm - 13.1" (12/22/84): fairly faint, edge-on streak 3:1 E-W. In a trio with NGC 1374 2.4' N and NGC 1373 6.8' NW. Member of the Fornax I cluster.

400/500mm - 18" (12/17/11): fairly bright, fairly large, elongated 5:2 E-W, 1.4'x0.6'. Broad concentration with a fairly large brighter core. Forms a striking pair with NGC 1374 2.3' N.
