Xi Serpentis is the star the farthest to the south in the Serpens asterism. You are now in the eastern portion, called ‘The Serpent’s Tail’: binoculars.

The star to the northwest here, nu Serpentis, is a binocular binary with a ninth magnitude wide companion.

The asterism now climbs to the northeast, again briefly crossing Ophiuchus. Place omicron at the southwestern edge of your glasses. The star you see at the northeastern corner is nu Ophiuchi: binoculars.

From nu Ophiuchi move two fields to the northeast; you'll encounter eta Serpens in a rather lonely part of the skies: binoculars.

From nu Ophiuchi you can also find M16, which is southwest about eight degrees.
