A striking little group, the 6.4 magnitude HR 1944 at the center of five 8-10th magnitude stars within 2' at least three of these are ~1" pairs as noted by John Hershel in 1874 and listed as HJ 3780

WDS lists companions up to I here designating HR 1944 as A and working from there, picking apart the Gaia EDR3 data shows this is not a single group as some stars have notably different parallax, while others appear to be associated.
