Lewis Swift discovered NGC 6435 = Sw. IX-86 on 15 Jun 1887 and recorded "eeF; vS; R; vF double star near following." His position is 2' too far northeast, but the double star, which is 2.8' northeast, clinches the identification. Swift relayed the discovery directly to Dreyer, who assigned it to list VI in the NGC, but the discovery was not published until a couple of years later in list IX (along with others he didn't include in list VI).

400/500mm - 17.5" (7/21/90): faint, very small, slightly elongated, small bright core, stellar nucleus. Forms a pair with CGCG 300-059 5.2' ESE.
