Seen again on the 6th of March 1781. The distance between these two clusters is therefore about 2000 light-years. Only one variable is reported in this cluster. The brightest stars of the cluster are red giants of approximate 10th magnitude. They give the feeling that the cluster is loosely concentrated when first viewed through an instrument.
Red giants are remarkable as well.
