NGC 6193
open cluster in the constellation Ara
NGC 6193 (also known as Caldwell 82) is open cluster containing 27 stars in the constellation Ara, visible to the unaided eye. NGC 6193 lies at the center of the Ara OB1 association, which extends over a square degree. The cluster is associated with (and provides the energizing radiation for) neighboring regions of the nebulosity NGC 6188.
Cluster members
NGC 6193 is dominated by two O class multiple star systems within 10" of each other at the centre of the cluster, and a probable binary B0 giant. There are at least 20 other early B stars in the cluster, of 9th and 10th magnitude.

“NGC 6193” enters the record as open cluster in the constellation Ara. Crown Archives preserves that source wording while asking what cluster and constellation can confirm, complicate or overturn.
Why this record matters
“NGC 6193” is worth following because a concise public description often conceals a longer documentary argument. Here, cluster and constellation provides the most credible route into that argument.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Aug 23, 2026. The linked authority identifier is Q731070. None of the 0 selected statements returned an explicit reference.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
