John Herschel discovered NGC 526 = h2408 (along with NGC 527 = h2409) on 1 Sep 1834 and recorded "pB, S, rather a doubtful object. The preceding of two [with NGC 527]". On a later sweep he noted "vF;; S; lE; this is the "doubtful" neb of a former sweep." This double system consists of NGC 526A = PGC 5120 and NGC 526B = PGC 5135.

400/500mm - 17.5" (11/1/97): initially NGC 526 appeared as a very faint, small glow, slightly elongated WNW-ESE. After extended viewing, it resolved at times into a close double system with NGC 526B = MCG -06-04-020 = PGC 5135, [35" between centers] that was oriented WNW-ESE. Both galaxies had very small brighter cores at moments. Forms a trio with NGC 527 3.1' S.
