Description:
Easily located in a group of stars that forms the top part of the
“sword.” There are 3 stars in a flat triangle, this is at the
uppermost end. Also, there is a nearby Y-shaped asterism that almost
directly points to this pair. Couldn't split at lower powers, barely
split at 72x in momentsx of good seeing, clearly split at 120x.
Both members appear blue. A very tight pair only a few seconds apart
and the secondary is quite faint. For these reasons I did not attempt
a measurement.
