Lewis Swift discovered NGC 6387 = Sw. IV-53, along with NGC 6385, on 22 Jul 1886 and logged "eF; S; R; nf of 2 [with NGC 6385]; this and the preceding point to the bright star about 8th magnitude." His position and description matches CGCG 300-037. This is a compact double system (not resolved in my observation) O.30'x0.22' and 0.25'x0.18'.
400/500mm - 17.5" (6/18/88): faint, very small, round, weak concentration. Close pair with brighter NGC 6385 3.3' WSW.
