John Herschel discovered NGC 6322 = h3673 on 1 Jun 1834 and recorded "vl cl VII. class, of loose st, on a v rich ground of S stars. The chief *, 6m, at the nf edge taken. The next sweep 2 nights later he logged "Coarse B cluster VII mainly included within an equilateral triangle formed by 3 B stars 5 and 6m. The nf of these taken."

200/250mm - 8" (7/16/82): consists of a near equilateral triangle of mag 7.5, 7.6 and 7.8 stars (sides ~7') with roughly 12 faint stars scattered nearby, moderately large.

300/350mm - 14" (4/5/16 - Coonabarabran, 73x and 178x): very distinctive, eye-catching cluster outlined by a very bright equilateral triangle (sides, 6', 6', 7') consisting of mag 7.6 HD 156189, mag 7.5 HD 156292 and mag 7.7 HD 156234. In the interior is a 34" pair of mag 9/9.5 stars, along with a 16" pair of mag 10.5 stars (both oriented roughly N-S). Another mag 9.2 star (HD 156271) is at the southeast side of the cluster. Roughly 50 stars total are resolved within a 9' region, including a number of mag 12-14 stars in addition to the prominent ones mentioned.
