William Herschel discovered NGC 4376 = H II-530 on 2 Feb 1786 (sweep 521) and noted "F, S." CH's reduction is 2' southwest of UGC 7498.
The RNGC misidentifies NGC 4378, located 50' south of UGC 7498, as NGC 4376. Listed in my RNGC Corrections #2.
400/500mm - 16" LX200 (4/14/07): fairly faint, moderately large, elongated 2:1 NNW-SSE, 1.0'x0.5', broad, weak concentration with no noticeable core.
