John Herschel discovered NGC 5470 = h1749 on 17 Apr 1830 and logged "F; mE; vglbM." There is nothing at his position by 1.0 min of RA west is UGC 9020, which fits his description. d'Arrest made two observations on the 25th and 26th of Apr 1865. He noted the 1 min time error in the GC and measured an accurate position.

400/500mm - 17.5" (5/10/91): very faint, moderately large, edge-on 6:1 WSW-ENE, low surface brightness, weak concentration but no nucleus, 2.0'x0.3'. An easy double star mag 10/11 at 21" separation located 4.5' S.
