John Herschel discovered NGC 3519 = h3314 on 14 Mar 1834 and reported, "Chief star of a pretty rich cluster, class VII." His position match the unequal double star HJ 4400 within a small cluster.

According to Brian Skiff, Ru 93 appears to be a string of stars on the northeast side of the cluster or may simply be a duplicate of NGC 3519. In a visual observation with a C-8, Jenni Kay observed about two dozen stars in a single cluster of 5' diameter with two brighter stars at the southwest edge. RNGC classifies the number as nonexistent, though the group was confirmed as a star cluster by Bica and Bonatto in 2011A&A...530A..32B ("Star clusters or asterisms? 2MASS CMD and structural analyses of 15 challenging targets.")

300/350mm - 14" (4/5/16 - Coonabarabran, 145x and 178x): roughly 80 stars resolved in an irregular 6' region (boundary pretty arbitrary), many of these arranged in chains or curving streamers of stars. On the west side is the brightest mag 9.7 star (mag 12.5 companion at 8" = HJ 4400) with a linear chain of mag 13 stars just west (oriented SW-NE). Another chain of mag 12-13 stars (oriented NW-SE) is on the northeast side. A mag 7.4 star (HD 96193) is roughly 8' SSE and a long chain of stars heads north from this bright star, reaching the south side of the cluster.
