Lewis Swift discovered NGC 6061 = Sw. III-90 on 8 Jun 1886 and recorded "eeeF; S; R; ee diff; 4th of 4 [with NGC 6053, 6055 and 6056]; 4 B stars south with the nebula form a cross like cross in Cygnus. Neb. placed as is Deneb Cygni." His position is just 4 seconds west of UGC 10199 and his description matches (three brighter stars just south form a parallelogram).
400/500mm - 17.5" (6/14/96): faint, small, slightly elongated E-W, 0.8' diameter, very weak concentration. Forms the north vertex of a near perfect rhombus (of sides 3') with three mag 10-11 stars in the NE corner of AGC 2151. IC 1189 lies 4.0' S
17.5" (5/28/89): faint, small, round, small bright core. Four bright stars form an upside down "Y" asterism just south including a mag 11 star 2.9' SE and two mag 10 stars 3.1' SW and 2.8' S. Located in the northern region of AGC 2151 with IC 1190: = UGC 10195 6' WSW.
600/800mm - 24" (8/1/19): fairly faint to moderately bright, fairly small, round, 35" diameter, small bright core, occasional faint stellar nucleus. Forms a near equilateral triangle with two mag 10.5 star 2.8' S and 3.1' SW.
24" (6/14/15): fairly faint to moderately bright, fairly small, round, 36" diameter, very small bright core, stellar nucleus. Forms the northern vertex of a near perfect rhombus (sides 3') with three mag 10.5-11 stars to the south. Several galaxies are nearby including IC 1189 4' due south, IC 1191 3' ENE and UGC 10195 6' WSW.
