Lewis Swift discovered NGC 6066 = Sw. IX-54, along with NGC 6065, on 19 Jun 1887 and recorded "eeF; vS; R; 2 pB stars near south both double; nf of 2 [with NGC 6065]." The discovery was communicated directly to Dreyer (indicated as list VI in the NGC) in 1887, but not published until 1890 in his 11th list, where he accidentally switched the declinations.

400/500mm - 17.5" (5/13/88): faint, small, round, small bright core. Forms a pair with NGC 6065 4.5' SSW.
