James Dunlop discovered NGC 6192 = D 483 = h3641 on 13 May 1826 and recorded "a cluster of very minute stars, of a round figure, about 4' diameter, following v Normae." He made 3 observations and his position is less than 4' north of center of the cluster. D 470 is probably a duplicate observation but his position is 19' too far east.

On 1 Jun 1834, JH logged "Cluster VII, pretty rich, irr R, gbM, 10', stars 12..14th mag, a straggling group." Two nights later, he called it "a coarse but rich cluster of stars 11.12th mag, which leaves dark lines unoccupied, forming sections (see fig 4, Plate V)." The central section in his sketch shows 4 circular wedges separated by dark lanes.

200/250mm - 8" (6/19/82): 20 faint stars mag 11-12.5 over unresolved haze, small, fairly rich with averted. Easy to identify in the field, though very far south for viewing from Northern California.
