Lewis Swift discovered NGC 6436 = Sw. V-74 on 25 Sep 1884 and recorded "eeF; pS; lE; v close n of the s * of 3 in a line." His position is just 50" north of UGC 10951 and the three stars are close southwest as in my visual description.

400/500mm - 17.5" (7/19/90): faint, elongated 2:1 N-S, even surface brightness. An extremely faint 16th magnitude star is just west of the core. Almost collinear with three mag 13 stars off the south edge which are aligned E-W.
